Actually you are right, in the case of simple tresspass, but not in criminal. If i could make a prima facia case that you entered with the intent of setting up a burglaryat least possible to use the warehouse as storage for something worse wink wink, which I could only establish with the contents of the camera. I simple state to judge at the time of the court hearing several weeks later, that I observed you with the camera and at the time I saw you, you were pointing it at a surveilence camera. That led me to believe it was more than simple treasspass. I believe at that time the camera becomes an element of the criminal treasspass. Were you photographing secruity on the site. I believed at the time your honor the the accused was photographing the secruity system of the building to plan a burglary.. I needed to process the film and use it in evidence against him. Since the camera was evidence in the crime by the simple fact that a police officer saw the defendant in a place he knew was restricted. The defendant was photographing the security system. So the camera was evidence and was fair game to be used as evidence and the images as well. At least that would be my reasoning for taking the camera into evidence and storing it till the trial. Im not sure your lawyer could get it back before the trial date. Then if I lost it would be sorry I made an honest mistake.
If I didn't want to go that route, I would just take the camera as property in your possesion at the time of arrest. Property to be safeguarded by ME. Until you are booked. You can't go into the slammer holding your nikon or your car keys. Oh that's right your car is In the impound yard anyway. I have to hold the camera till after you are arraigned before the magistrate or judge depending on how it is done in your juristiction. At which time bail will be set pending your court appearance. Then when you make bail you could claim your camera and other possessions. Then you could call have your lawyer drive you back to your car. Fat chance. Or you could call a family member to do it, and explain to them how you got tossed into the slammer to protect your right to keep a $2 roll of film or to keep you memory card from being cleaned.
Cost of lawyer... impound fee for towing the car.... bail bondsman cost... cab fare to the impound.. and a couple of hours in the slammer. All for a few shots of a deserted building.
OF COURSE IT'S THE PRINCIPLE OF THE THING
You would be surprised in the real world how few people think that kind of inconvenience is worth a roll of film .....
Sorry professor it just don't work that way. In some point the cost of keeping a $2 roll of film or not cleaning a card becomes prohibative. Explaining to your wife why it cost you 200 bucks for the picture of an empty warehouse is going to be hard, especially if she goes to court and finds out how easy it would have been for you to back down anywhere along the line.
Your statement about as is my right will come in and sound like a dodge to keep the illegal image. If you were breaking the law by being there it has to be an image gained illegally therefore an illegal image. I think that is how the law convolutes it.
And that isn't even going into the african version of the bullet in the head for the wiseassed photographer.
