That struck me as dumbness, too - although at the time I didn't know they were driving such high dollar wheels... it's just that after doing something like the bombing, is not the time to go try a stupid robbery.
That didn't add up.
“why did they rob a 7-11?”
They didn’t. They hijacked the car at the 7-11 location. The 7-11 was NOT robbed. The brothers actually withdrew money from Bank of America around 11pm.
Oh but media is telling us how smart they are, going to “prestigious charter school where many famous/celebrities have gone, suspect #2 is a 2nd year medical student, someone one else claiming one was studying engineering, maybe at MIT!”
