why should i be punnished for someone elses actions?

it would be like me taking your car away because some drunk guy killed a family last night... is that fair?

i go through all proper background checks and wait periods (if nessecary) when purchasing firearms, why should i be punnished because a few people get guns illegally and create mayhem with them?

i didnt cause them to do it, they did, i didnt help them, why punnish me?

people are taking the term "assault weapon" or "assault rifle", way too far... any weapon can be used to assault someone, even a butter knife, are we gonna label them "assault butter knives" now?
