I haven't seen Purge 2 or the second Planet of the Apes. When I think about the Purge if it was a real thing, it would be very costly. Now, I don't care about the loss of lives that will occur, that's the point, my issue is the collateral damage. The damage repair costs would be through the roof, and it can't all be fixed before the next Purge. Also, it leaves the country vulnerable to inside and outside attacks.
Maybe I'm just over thinking it. :P
