What you should do is retain a criminal defense attorney to represent you.To answer your question: if the police had grounds to search, then anything illegal they find is admissible and can be the basis for an arrest, charges, prosecution, etc. If there was a marijuana pipe in plain view, they had legal grounds to search--when police actually see drug paraphenalia or other evidence of a crime, they don't need a warrant. Since the search was legal, any evidence of other criminal activity, like burglarly tools, is legally admissible/usable.
