Just my opinion but I feel thats an incredibly naive and over simplistic view, criminals arent just going to be scared of guns or dead theyll just tool up for the job and shoot first. Dont get me wrong Im certainly not against firearm ownership as that would be hypocritical just the more guns the safer you are is a provable fallacy.
Edit, just for a successful recent European resistance against govenment slavery: The absolute fuckery caused by the yellow vest movement without a shot fired beginning 2018 France. If that population was armed imagine the bloodshed, it only takes one ND or unstable person to result in armed conflict.
