This afternoon I observed a female trying to gain entry into my home. I confronted the woman @ which point she was startled. She said that she was looking for the owner of the vehicle parked in the driveway. She proceeded to ask me if I was the owner. As I was speaking to her a male appeared to my right. Apparently he was acting as a lookout on my driveway. The male tried to diffuse the situation by saying that they were my neighbors. I immediately called the police. An airship responded immediately, while I was on the phone with the LAPD communication dispatch operator which informed me that he pilot had a visual on the suspects & ground units were en route to detain them. Minutes earlier the same suspects had tried to gain entry to my neighbors home & he confronted them. In excess of 30 minutes passes & I have not been contacted by the police. My neighbor leaves his home to run an errand & calls me 30 seconds after pulling out of his driveway to inform me that the suspects are on the corner down the street. I immediately call the LAPD; I demand to speak to the watch commander. I inform the desk officer of the situation & the desk officer refuses to transfer me to the watch commander & insists I need to speak to dispatch & transfers me. The dispatch operator informs me that the call was logged 35 minutes prior & that the notations state that the officers that responded are now back @ the station submitting reports & that in light of the situation I was right to request to speak to the watch commander. He questions why the desk officer would transfer me back to the dispatch & transfers me back to my local police station. I request to speak to the watch commander once again & the desk officer inquires as to the nature of the call, once I identified myself & explained the nature of the call he transferred me to the responding officer. When I inquired as to why the two suspects were not arrested the responding officer informed me that the female suspect said she was not attempting to gain entry to my home & based on that an arrest was not warranted. The female suspect informed the responding officer that they were soliciting. So I asked the responding officer if he felt it was normal to solicit in the back of the home with a bag of tools @ this point he became combative & informed me that had committed no crime & that if they return I could place them under citizens arrest. So as a home owner what I witness & report to the police has no merit. The LAPD will take the word of a burglary suspect.
