glad your encounter went well
Having thugs burst into my notice is not outside my experience.
Situations can come unglued only with participation of all of the involved participants. Step out of the ring and seize the high cover.
Cop could have crashed the gate, or detailed several deputies to sneak in and accost me. The dogs would have told me of the sneak, the result would have been my self defense.. "Y'all don't have to stand out in the rain", is an appropriate response to an over eager kid playing at being an authority.
