Former federal prosecutor Neama Rahmani told Fox News Digital he believes prosecutors will be able to argue successfully that the backpack search as well as officers' reading of Miranda rights were done within the law.

"I agree with prosecutors in this case that it was a legal search. And this is why there are some exceptions to the search warrant requirement. And the two that really would apply in this case are a search incident to an arrest or an inventory search. Both of those require an arrest. So as long as there was probable cause for an arrest, law enforcement can search anything within Mangione's wingspan," Rahmani said.
