Says who? The police?
I don't know anything about this story or how the general police culture is down under, but I can tell you this is a VERY dangerous attitude to take here in the states. The following statements apply to the US as that is where I live and the stories I read.
The police are NOT there to help you. They don't have to. This has been established by the Supreme Court a couple times. The police WILL lie. The police WILL kill you for no reason. The police will NOT be punished for it, in fact they will be rewarded and treated as heroes.
Now, let me say that my dad retired from the Illinois State Police as a lieutenant. My dad's uncle is retired from the ISP as well, he was a lieutenant colonel, district commander, and holds the state's record of most successful hostage negotiations. My cousin works for the ISP. My cousin's husband works for the county sheriff. I used to work for the ISP. I used to work for the local city police department. I used to work inside a county jail as a sheriff's department/911 dispatcher. I know a ton of cops. I would trust them all with my life. And I know if I were in deep shit they would do everything they could to help me, and some have. I have done the same for them, responding to two incidents in the middle of the night when I was home and listening to the police radio. Once I helped a cop being beaten up by a big drunk fucker. Once an officer stopped responding to status calls after calling out near a business to check on suspicous person. I didn't know what I was going to find, but I went to help, as generally in my town we have one cop and the nearest help is 15 minutes away at best, sometimes more. He had been knocked the fuck out by a board and was laying on his back behind the building. So suffice it to say I have a good relationship with cops I know.
That being said, I wouldn't trust a single cop that I don't personally know. I read the stories every day. I see the videos on Youtube. I see the self entitled gang members that hide behind a badge and try to walk all over the rights of their fellow citizens. Yes, cops are citizens too and should be subject to the same laws and expectations. I cringe when I see police departments getting grants for drones and armored assault vehicles. I get infuriated every time I hear the phrases "turn the camera off" almost invariably followed soon after by "Stop resisting!" Badges don't grant extra rights. The gun control issue is huge in the states right now, and what's so funny is if it continues in the current trend, those people who fought so hard to get it, won't have anything to stop them when it goes too far. In the meantime I'll keep sleeping with my Glock and keep my 29 round magazine loaded. Just in case. /rant
