Of course, opponents of gun rights are claiming this shooting proves America needs more gun control. Even some who normally oppose gun control say the government needs to do more to keep guns out of the hands of the "mentally ill." Those making this argument ignore the lack of evidence that background checks, new restrictions on the rights of those alleged to have a mental illness, or any other form of gun control would have prevented the shooter from obtaining a firearm.

Others are using the shooter's history of posting anti-Semitic comments on social media to call for increased efforts by both government and social media websites to suppress "hate speech." The shooter posted anti-Semitic statements on the social media site Gab. Gab, unlike Twitter and Facebook, does not block or ban users for offensive comments. After the shooting Gab was suspended by its internet service provider, and PayPal has closed the site's account. This is an effort to make social media websites responsible for the content and even the actions of their users, turning the sites' operators into thought police.
