No. I am using my memory. There were a lot of mass shootings when Obama was president. A lot fewer when Trump was president. And now it seems like it is starting back up again. Perhaps I am wrong about Biden and this last shooting was just a fluke. We'll have to wait and see.
However, the Dems are doing what they always do when ever there is a mass shooting. They start chomping at the bit for more laws which makes it seem like it is almost planned. The politicians need more gun legislation so they plan a mass shooting event in a vain effort to get the public on board. This is just a speculation and isn't a hardcore belief so don't ask me to defend it because I won't.
