So who pays the cost of rebuilding the property?  If shrapnel hits neighboring property, who pays for that?  Insurance?  So the homeowner gets to pay higher premiums?
 What happens when the police make a mistake and get the wrong house?  It's happened with SWAT raids and people have died. How do you pay for that?  No free lunch here.

I can't imagine at the rate of pay for most officers that the bill would be very large for a few hours.  I've been harassed by public safety officers that were glad to wait 2 hours for a search warrant.  I see them in Starbucks and parking lots all the time just sitting around.  Hours.  Free fuel and drinks.  And I'm paying for the bombs they purchase to put in their ordnance depots.

And yes, he eventually will have to either eat, drink, or defecate so the idea that he can menace non-stop forever and ever without some opportunity for control is ridiculous.  There was also a multi-year issue that society ignored as well.
