There are already laws against being drunk and dis-orderly... The people need no greater protection than that
Not only that, but there has for a great many years already been at least one cop on site during the game, any drunk situation can be quickly delth with, not that there has been any drunk situation mind you. Americans are extremely well behaved these day, more law abiding and docile than we have been at any time during my lifetime, so what is the justification for this removal of freedom? For this treating me like a child who is in need of a nanny? Of this assumption that we citizens are evil doers who require suppression??
