Im guessing the parent(s) or legal guardian(s) were not home at the time they booted in the door.
I would imagine that the surveillence they had running on the place knew when the moms/pops would be home?
Did they choose to kick in the door because there were no parents there?
What kind of prior history did this kid have that warranted a swat team to go to the house?
Everyone should remember this next time you leave your kids home alone at your house.... the things that are REALLY going on while your gone!
