I love chum caviar, but man, this is disgusting. If you are certain they are Russians, don't engage them.
Not because they are Russian, but because of the type of people they are.
They play by different rules until they land in the hands of Canadian law enforcement. Then they learn a few lessons.
O.R.R. is the best way to go.
Rieber, the stinky chum scenario won't deter them. They will find you and do to you what they do to the chum.
People like that often come from an environment of lawlessness. They think they are above the law until they aren't any more.
Not worth it, really.
