"But if some administrators and public-relations types, who are paid from the public purse, view transparency as a burden and The Globe’s reporting as “negative stories about police,” they have only themselves to blame."

If the stories in the press are both negative and true then the blame lies entirely in the lap of the police Their unwillingness to admit the truth to others and most likely themselves is clear evidence of  unfitness for their jobs. Their attitudes are no different than any other officer from the brass on down. This us against them attitude didn't start with the public and isn't held by the public today. All the public is asking for is an honest, competent police force. One who can do their jobs and treat the public with respect while respecting their Constitutional rights. Why is that too much to ask? We need a force well versed in the tactics of deescalation over situational control. Perhaps they could look to the British for training instead of the Israelis
