Yes! some people just like to be jerk's and take thing's that don't belong to them . I would mention to him that you lost your cam and that you intend on watching the area a little closer from now on ,just so that he know's and he might not be so quick to touch anything else from here on in .Don't accuse him just let him know what's been going on. I know it's only $65.00 but it's $65.00 that belong's to you not them.
This is actually 1 reason I haven't used a cam ,I'd love to put one out but I'm afraid of this happening.
