Hell no, and hell no. Dust is easy to brush off when you need it. Most citizens (good law abiding) sleep with a loaded weapon within reach, so I don't believe that a leo would try to enter in the wee hrs without good cause and then I guess it would be anybody's game. Make sure you have your security camera's on to alert you of any activity goung on around your property.
When I was in the academy we were instructed that warrants are to be served during normal daylight hours. To be able to serve a warrant at other hours required convincing a judge that it was absolutely necessary...and be able to articulate that such circumstances existed.
