Not really on topic but an interesting point given he mentioned the fan experience. Going to Mavs games used to be fun. But the level of police presents has ratched up very quickly over the last few years and has detracted from the fun of going so a lot of people I know no longer go. At the rate it is going you will need to be water boarded to get into the arena as part of the "security check".
Interesting, I don't go to many Mavs games, but was there about a month ago (the day before NYE) and didn't experience that at all. I haven't noticed a worsening trend at Stars games at AAC, either -- I remember about five years ago having an annoying security experience, complete with a line at some metal detectors, but in the past few years it's seemed to get quicker, if anything, for the Stars.
It wasn't exactly "fun" anyway, though, cause they couldn't buy a basket and got blown out by the Spurs... but that's a different issue!
I went to Mavs vs. Trail Blazers last Wednesday and only received a simple wanding after removing items from my pocket. I don't know anyone who is deterred by the police presence.
