They would never want to get into Egypt, they said. They would never give up staying in their land, they said. Every single last one of them would go back, they said. Right..

Eissa Sweillem entered Egypt
through the breached Gaza border — but not just to shop at stores. The
27-year-old unemployed Gaza man hopes to buy a fake Egyptian
identification card so he can get through security checkpoints and
across the desert to Cairo.

Egyptian officials say they have worked hard to keep Palestinians
bottled up near the border since hundreds of thousands poured across
after last week's breach. They are continuously stopped at checkpoints,
and most make it no farther than the first two towns: the divided city
of Rafah immediately at the border and El-Arish, about 40 miles away.

But some Palestinians, and perhaps also some weapons from Gaza, have made to other parts of Egypt, including Cairo.

Weapons? But they are only there to smell the sweet air of freedom. Why would they have weapons?

Well..

One state paper, Al-Ahram daily, quoted unnamed officials Wednesday as
saying Egyptian security forces had rounded up several armed
Palestinians across Egypt, foiling a number of terror attacks including
some planned against Israel.

[...] 

Most Palestinians trying to get farther into Egypt insist they are
merely seeking work, or even just fun — any escape from Gaza. The
territory has been largely cut off from the outside world since Israel
and Egypt closed their borders following Hamas' violent takeover in June.

Sweillem and some friends, staying at the house of an Egyptian
Bedouin friend, want fake IDs so they can get to Cairo to find jobs. He
and his friend Abu Malek said they once worked as laborers in Israel
but have not been employed since Gaza's blockade.

Each was offering $50 for an ID card. But so far, their Bedouin
friend, haggling over the phone late at night, had found only one with
a picture that looked similar to another of Sweillem's friends.

There is one of them though, that I do sympathize with:

His cousin, a 22-year-old Gaza high school dropout who gave only his
first name, Muwaffaq, said the young men wanted to watch belly dancers
in Cairo night clubs and taste alcohol for the first time. Liquor is
not allowed in Hamas-controlled Gaza.

"I will not give up. I will keep on trying until I do it," Muwaffaq said.

Imagine. No Alcohol. The Horror! 

Egypt arrests 5 palestinians who were planning a terrorist attack on Israel from Egyptian borders. Now do you people get why we can't have open borders? 

The poor penniless people of Gaza don't seem to be really that Penniless. Between buying basic survival necessities such as Cement, Motorcycles , and Dish receivers , they have spent almost half a billion dollars there in less than 2 weeks: 480 million dollars to be exact.

Now, them having that kind of money isn't a shock really. The people who can smuggle in weapons can also smuggle in cash and food, and everyone knows that Iran is picking up that tab, so the entire Gaza diet no money thing, well, was never really logical from the get go. But let's ignore that for a second, shall we? Let's take a closer look at what's happening economically in Al Areesh right now. In case you didn't know, the prices there have skyrocketed to ridiculous heights, with the majority of major goods scarce and economically out of reach for the average egyptian living in Sinai or out of stock. Gadosh has more details on this:

The
impacts on the Egyptian economy in the short term have already taken
shape. The duration of this crisis is also directly co-related with the
negative shock the economy might take.

I am sure it doesn’t need an economic genius to realize the impact of the increase of population of the North Sinai province (Arabic link to official website) from 306,790 residents to over a million. The influx of around 750K Gazans to the North Sinai
province has resulted in a massive increase in prices with in the
province. One resident of the province outlines the following changes
in his expenses since the influx of the Gazans:

Product
—- EGP Before Breach – EGP After Breach – % Increase in cost

1k
cream cheese — 15 – 70 – 466%
1
can flava beans (foul) — 1.5 – 15 – 100%
1l
vegetable oil — 9 – 30 – 333%
1k white sugar — 3 – 15 – 500%
transit
— 1 – 5 – 500%
1 pita bread —0.15 – 1.5 – 100%

Rumors
have been circulating in the last few days; that the shortage of goods
and products accompanied by increase in price, has reached the 3 Suez Canal
provinces. I can’t think of a more direct and worst impact on the
average Egyptian in the short term than this massive increase of prices
outlined in table above.

So you can imagine that the average Egyptian there, making approx. 300 egyptian pounds a month and who requires a minimum of 2 pieces of pita bread (Regheif el 3eish ya3ny) a day would end up spending 90 EGP, which is 30% of his salary, on bread alone. That's not even counting or factoring in the concept of him having a family or even wanting to get anything besides bread. On the other hand, the government has stopped allowing any food supplies from reaching Northern Sinai, because they figured if that area ran out of goods, then the majority of Palestinians would end up going home without the egyptian government having to exert any violence to do so. While this approach is smart when it comes to getting the palestinians out,  it's leaving the Egyptians residing there out in the cold as well. With no goods in stores, whomever didn't stock for food at their homes is now literally starving, with no way to remedy the situation until the Gazans leave. 

This has, naturally, caused some of the Gun-toting-Sinai-residents to express some, ehh, resentment, in regards to their palestinian brothers:

Armed Egyptian Bedouin opened fire in the air to warn away
Palestinians, highlighting growing anger over food shortages and price
rises triggered by the breaching of the border wall with Gaza,
witnesses said.

The confrontation in the town of al-Joura occurred as residents on
the Egyptian side of the border said shops had run out of goods since
hundreds of thousands of Palestinians poured into Egypt when Hamas
militants blew up the wall last week.

"The stores are empty and what is available is so expensive," said
Youssef Ali, a Bedouin in the divided border town of Rafah. "The
Bedouin are poor. The income of many Bedouin is not more than $30 a
month."

[...]

But the emptying of shop shelves and a block by Cairo on new
supplies has prompted thousands of Palestinians to go home since
Sunday, with some saying it was now easier to shop in Gaza than in
Egypt.

"The places are closed or empty. I am going back empty handed," said Mahmoud Mansour, a 52-year-old from Gaza City.

Rafah residents and shopkeepers said the price of tea and some
other goods had tripled. A pack of cigarettes had increased to 5
Egyptian pounds (90 cents) from 1.5 pounds.

[...]

Many Egyptians say they are suffering since Cairo began blocking
supplies of food, petrol and medicine to the Sinai peninsula to
discourage Palestinians from crossing into Egypt.

"There were too many people and too much money coming in. All the
food is finished and the petrol is finished," said 36-year-old Mohamed
Farah, an Egyptian government employee.

Many shops in Rafah were shut on Monday due to lack of supplies and even those that were open had nearly empty shelves.

Mohamed Suleiman Mahmoud, who owns a small supermarket, said he had
ordered 20,000 Egyptian pounds of cheese, milk, fruit and vegetables
but the shipment was still being held up by Egyptian authorities at a
bridge linking Sinai with mainland Egypt.

A Reuters reporter saw hundreds of trucks carrying sugar, rice, medicine, livestock and carpets at the bridge on Monday.

And they are not getting through until the border is sealed again. And it better be soon, or else the Bedouins will engage in fire-fights with the palestinians, and things could end up getting ugly pretty damn quick!

The Egyptian authorities are freaking out over the idea that Palestinian Hamas Fighters might have infiltrated Cairo, and they have a good reason to be worried, with the arrest of 20 Palestinians carrying explosives at the borders, so they have started a man hunt all over Egypt:

Security services in Cairo, Giza and the border cities close to
Sinai have launched a wide campaign in the streets, hotels and
apartments in search for the Palestinians who succeeded in penetrating
the Rafah crossing to Sinai and the provinces.

Eyewitnesses
told al-Masry al-Youm that security forces are searching taxis and
trucks and are talking to passengers to identity them from their accent.

A
security source who requested anonymity said that security directorates
had instructions from the Ministry of Interior on Thursday to collect
the Palestinians from streets and hotels and detain them in preparation
for sending them back to Gaza. Also hotel and apartment landlords were
ordered to report to security if any Palestinian asked for housing

Following that, egyptian authorities arrested over 3000 Palestinians who were trying to reach Cairo and other cities all over Egypt, some of them even reaching Upper Egypt, which goes against the "we just want to trade and buy supplies story". What they were there for has not been announced, and is now open to speculation.
