They will certainly not have zero effect. Will they eliminate gun violence all together. certainly not but then again it is only the gun proponents who use the argument that because measure will not eliminate all gun violence that they will have no effect.
please provide the data that shows what percentage of crime these laws will reduce (there isn't any because its not a problem to begin with with "ghost guns")
guns are basically untraceable after first sale the cops can trace it to the dealer once sold privately then its gone trail ends same as in Canada with non restricted
"ghost guns" are not a thing they are not a problem they are going after something that they make sound scary but has no bearing on overall crime stats its cheaper and far easier to buy a factory made gun. Red flags laws WILL be abused by ex's or anyone who wants to fuck with you, gun show loophole? please try and buy a gun at a gun show without a background check (I have lived in the us for years)
just like the ban "assault rifles" (they are semi automatic rifles NOT assault rifles which are full auto) which are used in 2% of all gun deaths in the us (more people die falling out of bed per year then from rifles) they are not the problem the dems and the media claim they are
handguns are used in most gun deaths in the USA rifles are not even close a few hundred deaths per year vrs many thousands with handguns
this will go to the supreme court which will likely strike it down
