hawaii also said it runs from chroot so I was mistaken.

Size or legality is not the question, the point is that purely from moral standpoint you have obligation to make sure you do not accidentally cause harm to others, not taking precautions is just selfish and lazy (and casts doubt on your skills, maybe you don't do it because you don't know how to ? "lack of resources" is a sorry excuse; if you can't do it properly then don't do it at all [besides making a small faraday cage is cheap]).

Willfull harm to others is covered in my post above (again the legality is less of a concern to me than morality [never confuse the two])

Time for my "classic" martial arts analogies (bear with me, I have trained for over ten years; it's a major part of who I am), paraphrasing my teacher:

There must be no accidental injuries; if you accidentally injure someone then your skills are weak. If you on purpose injure someone then you are an ******* and may need attitude readjustment. But it's better to be an ******* than weak in skill. (seems like censors hit us, can't be hard to figure out a seven letter adjective that starts with "a")

He has also said that you must always know how much pain you are causing (we do plenty of pressure points and painfull locks) and again accidentally causing pain is a sign that you lack skill.
