I guess the "damages" claims don't arise from filming them, but from making the video public.

Still, it seems to me (IANAL) that the suit doesn't stand a snowflake's chance in hell. In particular, they reckon their damages not based on any actual damage, but on the earnings Afroman made from publicising them.

Well, that's what the report says; but it's from The Grauniad, and the quality of reporting in that organ has been declining rather quickly (whatever Wikipedia says about "reliable sources").
