[Suits]

With respect to the modern world that we live in and a knowledge of what you can expect to have happen if you refuse the police entry to your house, what this man did was stupid, as his untimely death has illustrated.

That being said, I'm pretty damn sympathetic of his refusal to let the police demand entry to his private estate.

Provided that "there is a report of something criminal or possibly dangerous," the police have a long history of going wherever they damn well please.

The only thing to stop them is the fact that if they deny a person's constitutional rights, evidence produced might not be permissible in court, although its up to the judge's discretion and sometimes they deem the evidence as important enough to justify the illegal search.

There is the possibility of a lawsuit, but generally some harm needs to be illustrated.

If the police come in and look around and then leave, what harm has been done to you? Hard to prove injury in a tort court setting.

So, the police just do as they please, because generally, they can.

After a while, they just get into the habit of expecting entry. If refused, now its a "police stand off" and a possible kidnapping.

That being said, if he barricaded that doors, there is reason for the police to believe that subjects inside were being held against their will, a felony, and justification for forced police entry.
