Concerning the property of the tooling: if I bring my personal stapler to work, it's enough to taint everything I staple as my own property? how do we decide the property of the company paper I stapled with my staples? You can say it's reputed being the company property because you're on work time in company premises, but the whole principle of reputation is that you can bring a proof against (the stapled paper is your house insurance contract for example).
