Look for it. With a warrant.
And when you clean up the huge mess and repair/replace the prolific breakage consequential to them examining every conceivable nook and cranny it could possibly be hidden in, including the digging up the entire yard, you'll be disinclined to pursue that bluff again. ...and that's assuming they didn't find it.
What if they have trouble getting a warrant because the the “judge” that signed their rubber stamp warrents for your neighbors suddenly dissapears and other judges aren’t quite so eager to meet the same fate? What happens when the body of the officer that gave these orders to his command is found with ample evidence of citizens displeasure. neo-gestapo comes home only to find his family missing because they feared for their lives? That sure is a nice house you scrimped and saved to buy officer...sure would be a shame if something happened to it. The point is that they wouldn’t be magically immune from the consequences of their actions and it shows historical blindness to think that Americans would just roll over.
