Again, that's not why they carry pepper spray.I said it before. All they had to do was walk to the back of the streetcar, pull down on the rope to disconnect the power. They had plenty of time to do it. As they did to hit him with pepper spray.
If you want to employ a less-lethal measure, a taser, with lethal over watch (as in, someone beside you with a pistol drawn), is the appropriate response. Anytime a weapon is involved, there is the potential for thinfo to go south very quickly and having a lethal option available and ready, should it be necessary, is good practice.
