Yes. Anythig that has been 'discarded' is considered to be trash and can be lawfully seized, searched, or impounded without a warrant. .
the Fourth Amendment
Only if you let them. If they don't have any warrant, they can only search you IF they have your permission.
If they have a warrant, they don't need to ask. It also depends on why and where they searched the car, but generally, no.
a search warrant Also- I believe a Game Warden does not need a warrant.
Yes, it may be possible to sue if your home was inappropriately searched without a warrant. If law enforcement conducted a search without lawful justification, it could be a violation of your Fourth Amendment rights against unreasonable searches and seizures. You should consult with a lawyer to evaluate the specific circumstances of your case and determine the best course of action.
The law has the right to search a vehicle with or without a warrant.
No. If the search warrant is invalid and they illegally searched you or someone you know (like without reasonable cause, or without the warrant) then they can't use any evidence against you. To the best of my knowledge, anyways. I don't know how many ways a search warrant can be wrong though...if they were searching for like, pot, but found cocaine, they CAN use that though. Or a gun, or something like that. If they have the warrant, they can use it. If they searched without the warrant, its invalid and inadmissible 100%.
Yes. but they have to have probably cause to do so.
A Blanket Warrant is a warrant that allows police to search multiple places for evidence without saying exactly what they are looking for. This comes from a judge usually on Murder or Drug charge cases. More information is necessary in order to answer. I have never heard of a "blanket" warrant or any warrant that does not specifically state what is being searched for. As far as a specific location where a search may be conducted - as long as the warrant describes the premises to be searched (street address - name of business - lot & plot number - etc) there is no requirement that it state SPECIFICALLY WHERE within the premises may or may not be searched.
The rules would be the same as a car, due to the mobility of a boat. So with probable cause, it could be searched.
Yes, if there is consent by the minor, probable cause, a warrant, an arrest, or other authorization to search them
The warrant must specifically state the area of the home to be searched. If that area includes the locked safe then a separate warrant is not needed. It could also depend on the items being searched for and whether it could logically be located in that safe.
