>>It’s a special event, not normal duty and they should have some choice.
The article doesn’t say that it was an off-duty or overtime type of assignment. It sounds like it was just a regular duty day for the 30 officers assigned.
You’re making the wrong argument. The LEO’s refusal to participate in the event is justified by his moral conviction. What should concern you, however, is the statement released by the dept declaring his beliefs against sodomy to be that of “bias and bigotry”.
Rationalizing this type of tyranny through impartiality is a sure way to Hell.
