I know Matt Davis well. When I was a baby lawyer my firm lent out associates to muni court to prosecute traffic citations to give us trial experience. He wrote thousands of BS tickets per year and he and his buddies were scamming taxpayers with overtime. I wrote about it at the time on Hornfans.
He and his buddy would write a massive amount of tickets at speed traps. Often putting each other as witnesses. So they would be called to court multiple times per week. They would sign in at 8 am when court started in multiple courts. Then give the bailiff there phone numbers. So they would be earning OT pay starting at 8 am. Then they would disappear to go work side security jobs, and when we would try and call them as a witness the bailiff would say they were unavailable or in another court. In the off chance we could get them to show up, they would say they needed their other cop buddy listed on the ticket as a witness to make the case. They would never be available. So we would end up having to dismiss all their tickets. These guys were fleecing the city for hundreds of thousands of dollars in OT. Everyone in the court knew exactly what these assholes were doing. One assistant DA reported them. Matt Davis stalked the assistant DA and found out where he drank. Gave him a DWI charge in retaliation. That scared most off.
It was Davis, an asian cop I cannot remember his name, and another cop named Running. The Chronicle finally reported on them and noted they had fleeced the city out of a million in OT. It was more than that. Davis was writing about 10,000 tickets per month. So many of us probably were ticketed by him. He pulled me over on Allen Parkway once with a line of other cars with his buddies. I was not even speeding. You can recognize the prick because he always wore Oakley sunglasses.
