As I've related to you in PM's, Lady...my exp with law enforcement was ineffective till the fella broke into my house by smashing thru a glass door with a rock, coming after me with a gun. I escaped to the neighbor's driveway where he cornered me and pointed the gun at me several times trying to shoot me. The only reason I'm alive is that the gun jammed. (I think I had a guardian angel.) The neighbors in whose driveway I was trapped called the police. It resulted in one of those SWAT type stand-offs. The police trapped him after he kept putting the gun to his mouth trying to shoot himself (obviously knowing the gun wasn't going to go off!) He actually was so crazy he got the gun away from them as they wrestled with him.
I had been stalked incessantly by this fella for months, calling the police, with no effect. Only after this incident did he get jail time.
Please be vigilant in your safety.
