Where people are known to gather with guns can be attractive to criminals.
City of Chicago Attorney
April 4, 2011
Starting at about 29:15 in the recording of the oral arguments.
[I couldn’t quite figure out what the attorney’s name was perhaps it was “Feldman”. But that doesn’t matter as much as he represented Chicago and that he and probably others that wrote the Chicago brief had never been to a gun range yet proclaimed they knew enough to justify banning them in the city.
I question the factual basis of the above assertion and even if it were conceded as a fact that would not be sufficient grounds to infringe upon the specific enumerated right to keep and bear arms. Using the same logic as above they could also ban parking lots because they can attract car thieves, grade schools because they can attract child molesters, and banks because they can attract robbers. I view the statement above just as bigoted as saying places where people with dark skin loiter attracts an illegal drug trade hence those kind of people are not allowed to loiter on public streets.
It was very pleasant to hear the attorney get slapped around pretty hard by two of the judges.
