Can We Start With the POTUS?

So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior. Neighbors and classmates knew he was a big problem. Must always report such instances to authorities, again and again!

I don't know what's weirder:  the sentiment expressed in this tweet, or the fact it has a "parent" tweet about DACA.  Except maybe Trump wanted to say that mentally disturbed students are immigrants, too.

The argument here, of course, is that we can't control guns, so we need thought control for people.  You can't be restricted for owning guns, you can be restricted for what you think.  Seems reasonable, right?

And does this apply to Rob Porter?
