I am no army general or special forces specialist but one has to wonder why is throwing a grenade or any other aggressive action is the first line of action for any highly tactical large team with arguably the world's most advanced tech?

The consequences of the situation is perhaps up-to-debate but that is missing the point, the SWAT teams shouldn't be acting reactionary and out of fear, they should be, well, tactical about the situation and not burst into homes and hotels like they're in war-zone doing a Search and Destroy.

Don't they have thermal cameras at the very least to take a peek inside? Marksmen who could take a look inside? Someone who can listen in?

Very sloppy operation if they just shot a guy standing in the open.
