No they cannot come into your house with out a warrant unless the have probable cause.
Yes a police officer does need a warrant to come into your house, by force. But if the officer would ask to come in and you reply yes, he can come in without a warrant.
Of course not. At the very least they are guilty of TRESPASS, and if it was done with a criminal intent, they could be charged with BURGLARY. -------- BUT if it is police or any other federal person they can come in uninvited with a warrant and do want they want
If the police officers have a search warrant or an arrest warrant, then you have to open the door. If they have come to ask questions or for any other reason without a warrant, you do not legally have to open the door.
I think they can walk the premises but i don't think they can enter your home without a warrant.
Will the police come to your house on a bench warrant for a failure to appear at cost and fines hearing
Yes.
The police do not have to actually have the warrant in their hands. All they need is to have knowledge that it was signed by a judge and issued and this info can come via phone or police radio.
Yes, depending on the circumstances there ARE instances when they may legally enter without a warrant.
if you have a warrant the police can arrest you regardless of where you are best bet is to call the department that has the warrant and try to come to a conclusion on how to solve the warrant before they do arrest you and it is on their terms
If the police at the door have a valid arrest warrant, then you must produce the son or face obstruction (or whatever they call it in you jurisdiction) charges yourself. If the police at the door do not have a valid arrest warrant, you do not have to produce your son. In the case that the police have a valid search warrant for your premises, you can't deny them access without facing obstruction charges. If they search, they will probably find you son.
As often as they want until the warrant is taken care of.
