If the initial results hadn't been so terrible the bumbling of these two idiots would almost be comical.
Ambush a cop to steal his gun, unable to get it out of the holster.
Carjack random bypasser, force him to use his ATM card to get money, then stop at
two other ATMs because they don't realize the daily limit isn't for a single location.
Brag to the hijackee about being the bombers & tell him they are headed to NY, then leave him attended when they stop at a *gas station so he runs off.
After their spree of crimes they stop for food/gas and go ahead and pay with cash (instead of just driving off with a full tank).
Older brother heaves a bomb that lands closer to him than the cops, decides to charge the police line, gets tackled....and then gets run over by his own brother who decided to high tail it.
*Not directly related but the fact that the gas station was already in the process of being robbed when they arrive almost tips everything into the realm of farce. Can you imagine the story when the kid working the cash register retells it? "So there I was being robbed....when the Boston bombers walk in and buy some skittles."
