I saw this at another website I go to. One story is that the women had been traveling by bus and at a rest stop, they were approached by a group of men and felt threatened with sexual assult by them, so fled onto the motorway. It is one of the most horrible police related incidents I have ever seen.
Like many, I suspect they have some seroius mental illness possibly combined with use of illegal drugs or maybe even bad side effects from prescribed drugs for their mental illness. The cops were in a very difficult problem and were being filmed by some kind of police TV
program so their options to deal with it was even more limited. Last week in NY City, a cop there 'tazered' a mentally ill man who was nude, climbing on building fire escape and other building parts and after being tazered fell 10 or so feet landing on his head to his death. Of course the cops got into big trouble, the NYPD
has to do emergency retraining as to use of tazers of their officers at great cost, in a matter of days a massive civil lawsuit will be filed by the man's family.
Apparently one of the women had been charged earlier in the year with murder, but was on bail pending trial or a plea. I suspect her mental illness/drug use may a factor in that too.
