Opis 1:

How to rob a bank?

I and my partners made a good plan of getting rich. First step was to get the needed items like guns, bags for money and masks. It wasn't difficult since my wife's ex boyfriend runs a weapon shop.  Next step was to get into the bank at night. So we broke in and we had to act quickly. Everyone in my group  went to get the money and I had to knock out the guard who appeared nearby. Suddenly we heard the sirens which meant that the cops are coming. I told my buddies to hurry up and we jumped out of the building with bags full of cash, got into the black van and escaped.

Opis 2:

Daytime about 6.00am near the biggest bank in country. Mark and Robin put masks on their faces then they crashed into the builing, firing the bullets towards the ceiling, shouting ,,IT'S A ROBBERY, Everyone on the floor, workers put the money in the bags!!". Mark took the packed cash and noticed that one of the hostages called the police. He was silenced by hit on his head but it was too late, cops were on their way. Robin and Mark quickly got out of the building hopping into the black Mercedes. Then they escaped because they were too fast.
