Joe,

If you are referring to the entire force, I agree.  But, if it's true that some cops felt threatened and allowed the crowd onto the premises, well... that's unfortunate.

As for "Trump is to blame"?  Perhaps he's answerable for this or that, but unbiased historians will drill into the behavior of the F.B.I., D.O.J., Fourth Estate, DNC, RINOs, MSM, feckless mayors, grossly incompetent governors, China and the hoards of plastic bureaucrats.  I suspect they'll conclude the Peter Principle was pervasive throughout all of government, the print media, social media, and the gurus of tech and A.I.; that, along with an uninformed electorate.  

What other reason can be attributed to the election of a confessed felon (bribing Ukraine), who conducted his campaign reading one-liners from a teleprompter, whilst sitting on a chair next to a basement water heater? Or,

Two lousy senators from Georgia being unseated by two really lousy senators?
