Why did Highland Park Police encrypt their radio?

Can Middlesex County reverse the encryption decision?
It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by Middlesex County officials are policies those officials can revisit when constituents press for it.
What can I do about Highland Park Police encryption?
Three things carry weight, in this order: a public-records request for Highland Park Police's encryption policy and radio recordings, a turn at the microphone during Middlesex County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
