Really, police target vagrants in order to take drug dealers off the streets?  You clearly have no knowledge of  police tactics.   Vagrancy is a nuisance violation, and trust me most police prefer not to deal with them unless when absolutely necessary.   Are you stating police attempt to obtain  reasonable suspicion and then probable cause  to search suspect drug dealers by  claiming they are vagrants?   You have made some whopper of foolish comments, but this one stands alone as most ridiculous.
