I lived in Los Angeles for 36 years. I was there when the Marxist Socialist inspired Roberti-Roos Act was passed. I, as did Saxon Pig, fought it right down to the wire on a political level, but the fix was in. The Marxist Socialist inspired zombie media, all gun prohibitionists, lied and lied and lied 24 hours a day about the "assault guns" and it was impossible to counter the overwhelming propaganda from them.
The NRA and the State affiliate, California Rifle & Pistol Assoc., fought it assiduously, but the far left liberal Legislature/Senate passed the bill and a super left wing RINO Republican Governor, Pete Wilson, signed it into law.
(Wilson signed every anti-guns law the Marxist Socialist inspired legislators spoon fed him, including one that made some T/C single shot pistols illegal.)
As for those who complied, some obviously did, especially the competetive shooters who used the "evil black killer rifles" in competition, etc., but most people did not comply. Some "sport" shooters also registered their banned guns.
From what I've heard from some people who would know -- and although I can't prove it, I believe it -- only about 10 % of the banned guns were registered, if that many. I have no idea how many people I knew who did own them but refused to register their banned guns.
I left in late 1997 and could not be happier living in Idaho.
