They likely knew he was actively wielding bladed weapons.

I watched the full video. They were repeatedly told he didn’t have any weapons. The clinician just said the man was violent and kicked him.

I have no idea why they didn’t use less than lethal first, they talk about it but I don’t know which officer was tasked with it. It seems like they didn’t expect him to be armed when they entered.

Go to Applebee’s and order Four-Cheese Mac & Cheese with honey pepper chicken tenders. The chicken tenders are excellent but the Mac and Cheese is the most watery garbage I’ve ever eaten. Then you will understand the true skill of making delicious Mac and Cheese.
