I'm gonna split the difference on that - casual thieves are attracted to stuff, organized thieves do some research. I know about a pattern of robberies of film crews (an industry I used to work in) in my area - these can be profitable because camera gear in particular is quite expensive so a small well-equipped film crew is standing on the street with $10-20k worth of poorly-secured gear, which they probably don't care about losing because it's insured. The modus operandi is consistent enough that I'm fairly sure the thieves are working from city-issued permits.
