After today's shooting of National Guardsmen in Washington DC, the USCIS has announced it is suspending all visas and immigration processes for Afghan nationals.

That's a good start.

That would be for the best.

It's a little too late to do the right thing now, but at least maybe it can save some lives down the road. 

Not always. Sometimes it is preferable. 

Probably. The federal government needs to be prepared to fight back if they do. 

It is long overdue and should not have taken a shooting of servicemen and women. 

Send back their best men.
