This seems barely worth an article: the LAPD posted a violent assault asking people to identify the suspect, and YouTube (possibly an algorithm) suspended the account for posting violence.
Should violent content be allowed on the internet? I believe so. Should it be allowed on YouTube? I believe YouTube can decide: if they want to block violence, porn, and other 18+ content for everyone, that's fair and those people can post on the other sites. There's an argument that posting on YouTube instead of a less popular platform is necessary for LAPD to increase the audience and more likely identify the suspect; but I think there are better ways which get a higher-quality audience and don't involve exposing random people to a random assault.
