Being very right wing I am generally very supportive of the police. That said there are of course some especially the young ones with newly found power that give the police a bad name. The thing I dont like is harrassment of the public when the police dont understand the laws as written. Of course here that means the fact the ones that dont understand the rights of cyclist to use roads and hiways.
While I cycle for fun and exercise, a lot of cyclist ride for the fact that they have to. Some, like college students dont have a car maybe because they cant afford one. Some may be poor people that simply cant afford a car. Some may be drivers that have had their license taken away from them and are cycling to work. There can be any number of reasons why a person is legally cycling on streets and roads, and the police need to understand this and accord them the right to do so by local laws.
