How can there be a shooting in extremely regulated California when people cannot own guns?

Why are we not hearing anything about the leftist democrat that did the shooting?
-------------------

This reminds me of the Washington DC shootings by a socialist democrat bernie sanders supporter.
It was on the news for ONE DAY ONLY..........but only Republicans were shot......hmmmm.
------------------

You can be sure that if it was a Republican or an NRA member who had
done the california shootings, you would be hearing about it for WEEKS!........from democrats and Fake News....
