Make it illegal for a lone police officer to arrest an unaccompanied woman

Murders of women occur on a far too frequent basis however this is the first time where I haven't been able to say I would have done anything differently to what a victim did. People should be able to trust police officers, but have limited options for protecting themselves if confronted by a police officer. We believe the only way to protect women is for lone officers being prevented from being able to arrest a woman who is by themselves. Two police officers must be present for such an arrest.
