I'd say it's more likely kids picking it up, saying "What a piece of junk... mommy buy me a power ranger" and chucking it on the floor or lower shelf.
Honestly, the only reason I got a blonde officer was because his card was trashed... While I sort of sympathize with the plight of the carded collector, I also feel that the blondie in question would NOT have been there had his card not been crushed and bent beyond belief. Every other figure of his wave was gone anyway, and he's usually the first to go.
Still, I feel bad for a carded collector dealing with the bent cards and such... I try to hold some sympathy even if it's not my "style" of collecting. If someone bent up half the case though, I'd be happy to buy the bent up ones.
I was giddy to get that blonde officer.
