If MS maced BL, she would have had time to run away but she didn't so either her leg was injured to where she could walk, or she was in a locked closed area....say like a truck with no door handles.
I'm thinking someone defending BL or someone at the county court house is leaking documents the DA is giving to the defence to a reporter. It was reported that the defence wants a change in venue so he has to be leaking info for it to be reported.
The medical stuff is only coming from the police report, and I suspect the rumor mill is adding on to it.
I wouldn't doubt it a bit if BL had a allergic reaction to mace. This of course is only my opinion and not based on fact.
Some friends of mine were being searched once and the cop found mace in one of their purses and he told them it was "useless" in an attack. I'm sure there are exceptions but for the most part it probably is just a false sense of protection.
