They haven't stopped, just don't report all
Every weekend has had at least 1 report of shootings. They do tend to focus more on the young people that get injured or killed and I am certain they are not reporting anywhere near the actual amount of incidents.
Gun control laws are silly in that they only deter "law-abiding" people. The majority of shootings are done by gangs or people who acquire their weapons through UNLAWFUL means. People fall on the demand for Gun-control laws because they need a crutch to lean on. They want reassurance that their actions are helping the situation and are easily sated by the band-aid solution that falls off easily when put to the test.
