ummmmm...no, we should not be encouraging Trump to "do something to achieve law and order"...
he has deployed to Portland, OR, federal agents from DHS/CBP in camo military uniforms without identifying insignia or ID nameplates and in unmarked vehicles, without consent of state and local government leaders, to stop protests in that city...protests that are Constitutionally protected exercises of citizen's 1st Amendment rights...protests have been mostly peaceful, with a few criminal acts of property damage that local authorities said were under control.
they have stepped up law enforcement efforts to quell the daily protests by use of tear gas and other use physical of force...federal agents have "arrested" some protesters, forced them into unmarked vehicles and transported them without probable cause... beaten, tear gassed and shot others with rubber bullets...
the spokesperson for these federal troops said they were there to protect the federal buildings...yet the officers have strayed way beyond a property protection role, advancing many blocks into city streets beyond federal property...even as local law enforcement agencies request that they stop...
this is what federal government over-reach looks like, the kind that 2nd Amendment groups continually warn about, but our friends on the right have been supportive... or silent, which is tacit approval
