And this is where you are wrong, just showing your hands and having another unidentified person swear upon God almighty through a window doesn't relieve a LEO from his sworn OBLIGATION to the city/county/state he protects, LEO's are Sworn to enforce the Law, Laws, case law and Policy dictate how much and how far an Officer must go in order to enforce the laws put in place by Legistlators YOU vote for.
As has been said, cops roll up to this house, see two people stating that everything is fine nothing is wrong through a window, meanwhile inside the house there is a woman bound and dieing, sound familiar? Research the amount of times Cleveland cops were called to Ariel Castro's house and didn't do a thorough job investigating the report, which way do you want it?
Clearly spooked? Get real, I think you would have a better case if you stated these people were Illegal aliens, these people had an agenda and got exactly what they wanted, the only problem is they do not know the law.
Cops don't like to be filmed? yeah sure some don't like it when someone they are interviewing has a camera up but in all honesty I don't want your hand at shoulder level either when I am talking to you. Normal people do not have their hands elevated in a position where it could be employed to strike someone while having a conversation! The reality is that a huge portion of LEO Work is in fact done on Camera, every LEO on earth has had the discussion about how would you like a personal camera on your uniform, some have it now, its not just to protect the citizenry its also to protect the officer in fact as these incidents become more popular more and more cops are carrying them, I bet inside of 10 years it will be Policy in many departments, now lets put this into perspective, how would you like to go to work knowing that your company car had multiple cameras in it and you were also required to have another camera on your uniform?
As I said before if the persons in this video had only gone outside nothing would have happened, NOTHING.
