Can you still get in trouble for growing?!!!?

I have a friend in Michigan that had cops come to his house for unrelated issue. When the cops entered they found a grow room. Obtain a warrant and took everything. Only like 20 plants ready to harvest.
Should he worry

If it was for an unrelated issue it is surprising they got a warrant. Sounds like there is more to the story. Keep us posted.
