I lived in Houston for 35 years. Every time the city elects a Republican mayor the police start writing tickets left and right. When Lanier was elected some years back the city actually had to put on temporary judges to handle all the traffic court cases. When there is a Democrat in office however, you practically have to taunt the police to get them to cite you.
One woulddl think it should be the other way around.
But then again, follow the money...
