You forgot #6. Bad guy sees cops at door and flushes contraband and down toilet while police wait outside.

If the police were competent, they could guard against this by putting traps between the street and home or elsewhere to 'catch' the forbidden item.

Of course, dead citizens are just the price we have to pay for the "war on drugs".
