Could you clarify your use of "permitted" here? In the sense of "allowed", it seems redundant, since you go on to say that they were or were not forcibly dispersed.
The other option, more literal, is "they got a permit to do this protest", but there have certainly been plenty of peaceful grassroots protests that got no sort of official go-ahead and yet were executed perfectly fine on both sides.
There are peaceful/permitted protests that the police leave alone and occasionally support/join.
There are peaceful/not-permitted protests that the police disperse with various uses of non-lethal force.
There are Rioters that vandalize and try to blend with protesters but seldom directly confront the police - occasionally confronted by protesters.
...and then there's just tons of rampant looting with little police intervention.
Anyone blending these four distinct phenomenon is just doing truth and justice a disservice.
