Democrats sadly leverage shooting incidents for political purposes when it comes to tightening gun restrictions. But most of their proposed new gun laws wouldn't do anything to stop these tragedies. Instead, they'd limit law-abiding citizens' Second Amendment rights, which should never be infringed. Democrat talking points conveniently ignore the number of times citizens need firearms for self-defense.
Republicans at every turn continue to block legislation that would make Americans safer. At minimum Democrats want to restore the assault weapons ban that effectively reduced these tragedies before Republicans allowed the law to expire. There's no such thing as an uninfringed right to possess firearms, as proven by the numerous laws Americans accept in the name of public safety.
There's a 50% chance that there will be at least 1.41 small firearms per capita in the US in 2029, according to the Metaculus prediction community.
