I suppose if you wanted to get really nit-picky you could wonder about the wisdom of shooting it out with robbers while your young grandson is in the vicinity. But fuck it. The kid didn't get hurt. AND he received a valuable life lesson from his grandma. That lesson being, don't become a robber because THIS IS WHAT YOU'LL GET. That kid is on the right path in life thanks to his grandma Lulu. Gun control? FUCK gun control.
