"Because what it does is lower the standards by which our government can come after us.""When that confidence is shaken we have to slow down for a minute and make sure that the public sees us as an organization that they can trust," said Police Chief William Scott.The 10-year JTTF agreement was set to expire in March and policy could be revised.
