wanna know why??
it's cause they just beat up and trap a random pokemon outta know where! (i know police don't do that with ppl but wateves)
like for example ash and his pikachu are walking around some stupidly named city and they see a sparrow!
the sparrow isn't doing nothin just walking around and here come's ash telling his pikachu to kick the sparrows butt! and when pikachu does ash put's the sparrow in a pokeball forever! even tho the sparrow eventually start's likeing ash it's cause it get's bored and thinks if he acts nice ash will send him free for good behavior which happens when ash decide's to go to sinnoh BUT the sparrow is now stuck with professer oak in a machine (the PC thing) for life!
it's a just a joke i made up don't get me wrong pokemon is still ok (atleast the game is.....)
