The legislation would restrict gun owners from leaving firearms in a place accessible to minors; - Already illegal. It's called criminal negligence or child endangerment. Why do we need another law? (P.S. Say, my gun safe is accessible to my 16 year old son who has his own firearms in there - OMG I'm a felon!)
create a registry in the city of Cleveland that would compel convicted gun offenders to register with police once a year for four years - and what is the purpose of that and who would be covered as a convicted gun offender? If I got a 'trespass' conviction for bringing my gun into a store where they had posted but I didn't see, would I be 'on the list'?
limit gun purchases to one firearm per person per 90 days - If this is intended to address straw purchases then that's best left to the state level because doing it locally has zero effect. I think the purpose is just to irritate and drive down the profits of gun dealers locally.
The new ordinances might also incorporate past laws including: Requiring school officials to notify police when a prohibited weapon is found on school property - Every school I know already does this. Every school. Why do we need a 'consolidated' law? Address in school board policy.
allowing people to voluntarily surrender guns to police - As if the police would say, "Nope, I won't let you give me that". Please. Address in departmental policy.
Banning the sale and manufacture of gun replicas. -Fuck you airsoft guys, BB gun shooters, replica collectors, etc. Again, what's the point?
None of this makes logical sense. It's just the City of Cleveland trying to get the proverbial camel's nose under the tent. The liberals are all butthurt over preemption not allowing them to create a patchwork of laws criminalizing the behavior of the average gun owner unfortunate enough to reside in or travel through their kingdoms.
