Hmmmm. I'm trying to think of other "neutral" objects and whether one could be summoned to submit them. In a sense, supplying a murder weapon, or computer records implying a fraud, are also objects disconnected from the offender (unless there are fingerprints on the weapon). I guess the defendant wouldn't be obligated to volunteer the box, but could be subopoenaed to do so, same as with every other type of search and seizure.

EzPass

Walla. But EzPass is more a method of enforcement on the spot than a method of apprehension and conviction "leachar maaseh".
