[Marvel] Spider-man leaves criminals wrapped in web for the police to pick up. Can they be arrested?

Really this question is for any vigilantes who fight minor criminals.  They are often left subdued, sometimes with a note, for the police to pick up.  But with no evidence can they be arrested?  If so, how does the trial go when the hero doesn't show up to testify?

There's a **Spider-Man: Tangled Web** story called *The System* which revolved around that that premise.

The story is about the discovery of two webbed up thugs found near the scene of a robbery that led to a shop owner being put in a coma, but no witnesses or cameras in the area, save for Spider-Man. 

The investigating NYPD officers are shown to be fed up with Spider-Man because him intercepting, beating up, and webbing up criminals, then leaving them to dry before the cops can respond has given way to "the Spider-Man Defense": criminals take advantage of Spidey's controversial public reputation and argue their way out of charges by saying that Spider-Man simply assaulted them for no good reason, and that they only happened to be in the vicinity of various crimes, even suggesting that the Spider-Man was the real culprit and was trying to frame them. 

And since Spidey doesn't stick around to fill out any police reports, submit evidence, give testimony at trials, many criminals end up walking free because of the lack of clean and irrefutable evidence.

The story ends with Spider-Man leaving the detectives a photo he took with his Spider-Camera of one of the thugs trying to rush him with the baseball bat used to put the shopkeeper in the coma, which is apparently enough for the cops to put him away.
