Why he made the clock look like a bomb then ? And why was it making beeping sounds ? In movies u see many bombs that look just like that..

Its like you going to the GHETTO and showing off CASH and dollar bills. What u think will happen ? U will get robbed and maybe even shot...

Same here, muslim boy, makes a device look and sounds like bomb...Then he brings it to his classroom.. Looks like a bomb, sounds like a bomb and he is in a school. Are you going to think its "CLOCK" or "BOMB" ?
