Yours is a very important post. *No one* should be harassing BL's parents, and LE should disperse that crowd. If for no other reason, they are disturbing the peace for the other residents in the neighborhood. The L family should board that home up, hire a security guard to watch it, and leave. Perhaps at some time they can move back in, but who knows when, if ever. The mere fact that they are staying there is seemingly a nose-thumbing act, and just fanning the flames.
Even CL mowing the lawn seemed nose thumbing. He could have had someone else do that. What's wrong with these people? My opinion only.

If I were the Laundries I'd worry about leaving the property with only one guard given that the protestors have been banging on their door. But let's say they'd do it. I have NO idea what security guards cost. But apparently minimum wage in FL is now $10/hr. I'd think a decent guard would get at least double that. (Actually I think it would be more than double but I'll use double.) So $20hr x 24 x 7 comes to $3360 per week. And they'd have to pay for somewhere to stay like a hotel. Say they luck out and get a safe secure hotel room for &125/day or $875/week. Guard plus hotel each week = $4235
I really don't think declining to pay over $4000 per week to deal with those obnoxious "protestors," means the Laundries are thumbing their noses at anyone. Lots of people don't have an extra $4235 each week or nearly $15,000 per month to spend.
