Just went to pick up my son from work and the local Police are out in force tonight, a riot van and squad car, lights flashing stopped a group of people walking on the footpath, another squad car parked outside the rail station, looked in my rearview mirror had another sitting right on my tail. I saw my son just coming out the retail park, so I pulled over to pick him and police slowed right up and hung back a bit. I think because my son was wearing his company uniform, they decided to leave me and drove on by. Turned the car round and drove back home and on the way back passed 2 more police cars going in the opposite direction.
I don't know for sure but it's an educated guess that they are trying make sure that we all heed the government advice and stay at home.
