Well, let's face it. It WAS a private citizen that went outside, violating the lockdown order, who saw the guy in his boat.
Not saying the cops wouldn't have eventually found him, or that narrowing down the area didn't help because it did, but he could have been dead by that time too.
There's pros and cons politically. This de facto martial law psychologically conditions the population to live like this. Ultimately, it could lead to lack of resistance by the people when it's needed.' Er well that's happening already. Warrantless searches did not prevent act of terror, nor did the evisceration of our rights. People are being conditioned by these events laying down and giving up their rights instead of insisting its central govt to change its policies.
Getting tired of being told by people who live in gated communities say fences or walls don't work.
