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.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
