Police raided a farm in Christina Lake, British Columbia to find that black bears had been enlisted to scare intruders away from the premises. Two people were arrested for running a marijuana plantation. The ten or so bears did not pose a threat to police.
"They were tame, they just sat around watching. At one point one of the bears climbed onto the hood of a police car, sat there for a bit and then jumped off," said Royal Canadian Mounted Police sergeant Fred Mansveld.
In Canada, feeding bears is illegal as it leads to bears associating food with humans and increases the likelihood of bears coming into towns and cities to look for food.
One has to wonder whether the bears were guarding the marijuana or helping themselves to it. Link -via Arbroath
