That, and strip mall parking lots being his destination to shoot coyotes with his silenced AR15. Fear mongering at its best!
Silenced doesn’t help unless a subsonic round is used. A 300 blackout loaded very light with a silencer is still a very loud round. A .22 LR on the other hand will not be heard by the neighbors and if well scoped will do the job just as well. Even better if a bone of body mass is missed since a .223 will breeze right through a coyote without picking up a dent.
