Alternately, what could have been done is something more like Shambaugh did. Explain the situation politely and ask it to leave, or at very least for their human operator to take responsibility. In the Shambaugh case the bot then actually play-acted being sorry, and play-acted writing an apology. And then everyone can play-act going to the park, instead of having a lot of drama.
Sure, it's 'just a machine'. So is a table saw. If some idiot leaves the table saw on, sure you can stick your hand in there out of sheer bull-headed principle; or you can turn it off and safe it first and THEN find the person responsible.
