What can I do about Sullivan County Sheriff's Office encryption?
Three things carry weight, in this order: a public-records request for Sullivan County Sheriff's Office's encryption policy and radio recordings, a turn at the microphone during Sullivan County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
