I have 2 cams on my bicycle, and reported 14 incidents to the police between January and April this year. 12 of the 14 have had action taken. Mentally, knowing that they won’t get away with it stops me getting angry, and makes cycling more pleasant. It might also deter them from being arseholes in the future.

Yes, people should report crimes when they see them. Especially when they risk harm to others.
