I'm not surprised by the rubber stamped warrant. Cop shops are known to shop for judges that will just stamp off. I'm sure they didn't mention that it was a MRI business but the odor of weed even combined with high energy usage shouldn't be enough for a raid IMO. There should be some other evidence, especially in LA where it smells like weed pretty much anywhere.
I'm curious how this will go. I assume LA will settle out of court because they don't want a precedent set that they actually going to be responsible for private property damage during raids.
