That would be illegal. They have to follow due process.
Yes, police may come to your house if there is a warrant for your arrest.
yes
Police with an arrest warrant can enter the home of the person named in the warrant if they have reasonable grounds to believe he is on the premises. They can search the premises in any place the accused person would be able to hide (they couldn't for example, look in the drawers of a nightstand, because no one could hide there). Police have to get a search warrant to enter the house of a person other than the one named in the arrest warrant.
If they are instructing you to open the door and do do not listen to there commands you can be arrest for obstruction. If you are obstructing or hindering a police investigation they can arrest you. Also in some cases if the police come with a warrant you might not have to open the door they just might do it for you.
Define "bust" in. If they know you are in there, yes, they may enter - especially if it is what is known, in some jurisdictions, as a "forthwith" warrant.
What does the questioner mean by having the "physical" arrest warrant?If it means that, even though there is an existing warrant, but they just don't happen to have it in their possession - for them to act on the knowledge that the warrant exists is still lawful. They do not need to have the actual warrant in their possession in order to act on it.As in most cases involving the law, the CIRCUMSTANCES of the situation dictate what law enforcement can, and should not do. For example;If the police are in 'fresh pursuit' of someone and they run into the house they CAN pursue and arrest the individual inside.If they knock on your door - you open it - and behind you, they see the wanted individual sitting in your living room, they can enter and effect the arrest.
Yes. Depends upon the circumstances, for example, if the individual entered the residence to avoid apprehension and the police witnessed the act then they do not need a search warrant.
Yes. What do you think a warrant is??
they have to have a warrant to search your house and without it they cant come into your house but if you step out they can arrest you for whatever your charged with
Depends on the situation. If the police feel there is a need for emergency action or there is a life-threatening situation in the house then the police don't need a search warrant, they also have probable cause at their disposal.
I would think that if they knew that person was there......yes.
If they have a war warrant for your arrest and have due cause to believe that you are in a residence then they can execute that warrant whenever they like. If you believe there is an arrest warrant out for you and you do not want to cause your family distress, go down to the station and give yourself up.
