Kinda, but car thieves are retarded. My wife's MR2 was broken into and they stole the head unit (this was like, 2001) but didn't touch the subwoofers or amps... gratz on the $400 head unit but they missed the $3k in equipment. I'd say you never know what those retards are thinking and dark windows are the best defense so they just don't spy anything worth breaking your windows over.
In the 1970s we had a aquarium store that had a Blue Ringed octopus. Sold some exotic fish but that was not for sale.
