> So, again, you prefer leaving these people alone, despite the police having a reasonable idea that they're carrying a weapon? You know, I suppose, that people carrying a gun walk and carry themselves in a distinctive way.

"The number of stops increased dramatically in 2008 to over half a million, 88% of which did not result in any fine or conviction, peaking in 2011 to 685,724 stops, again with 88% (603,437) resulting in no conviction. Leading to the remaining 82,287 resulting in convictions. On average, from 2002 to 2013, the percentage of individuals stopped without any convictions was 87.6%." [1]

Not terribly distinctive. They got it right less than 1/8th of the time. If that is your argument, that they were only stopping people they think had guns and were going to commit a violent crime, it's a terribly poor one. The vast majority of people were detained by the police with no cause other than looking a particular way.
