That all depends on the content of the videos, combined with testimony from family and friends, prior legal run-ins, and the recent purchase of multiple firearms consistent with the content of the videos.
Immediate risk does not equal certainty, as some here would like to imply.
I think also time frame is important. I have been in LE for many many years...i have been in the same position as these cops...i hate it. Mental health is one huge grey area. These people have rights as well...and we have to balance those against public safety. Based on the backlash I see from this incident...cops are going to be expected to see the future...and peoples rights will be diminished. My 2 cents
