Arlington has seen its share of Black Lives Matter activism over recent months, with residents coming out to Mass Ave to demonstrate their support for greater racial equity and police reform. This week in front of Town Hall, a rally with a different focus: support for the Arlington Police Department, which the organizers assert has been in short supply. The Arlington Backs the Blue rally spawned a counter protest, which took place right across the street at the very same time. ACMi News was there.
