The Trump administration is setting a new norm, that wearing masks while being an armed law enforcer is normal.
Criminals will take advantage of this. It is nothing new that hardcore criminals disguise as police, but what is new is, this disguise can now be worn while being masked, and it will not look out of the ordinary.
Criminals will be able to abduct anybody anywhere while wearing police gear, guns, AND masks, and no one will be able to know if they are real or fake.
