My question involves police conduct in the State of: Illinois
I have had a hard few months with my roommate. Finally after not being able to take any more of her verbal assaults and out of control anger fits, I decided to move out immediately. When I returned to the house to get my things, she was there. Some words were exchanged between us and she got extremely angry and came at like as if she was going to attack me. I stuck my hand up in her face and pulled out my phone to call the police. She did not attack but she was very threatening. I basically ran into the garage and waited there until the police showed up.
Once the police showed up, I explained to them what happened and that I wanted to pack my things and leave but I was afraid that she might attack me. Then the police brought us both inside and told me to go upstairs to pack my things. To my surprise, the roommate came upstairs after me while the police were downstairs. She told me that she was "instructed to come up here". I was in disbelief. I felt somewhat comfortable because I knew the cops were in the house but I could not believe that they would allow this perp to be in the same room as me, unattended by the police. The whole reason I called the police is because I was scared of what this person was going to do and here they tell her to go upstairs into a room with me where we were away and out of sight of the police. I once again felt threatened and scared.
I believe those officers were negligent in doing this. Are my beliefs correct? Can I take any recourse against them?
