The only real difference is that by tapping first, I can honestly testify that I did knock and announce myself. If I am willing to lie on the stand, then it does not make any difference at all. Most cops who do this really do want to obey the law and still make arrests, so they try to find loopholes around it. It is called noble cause corruption in the academic research studies on this. Corruption caused by cops trying to do the right thing.george wrote:I really did not see much difference, the way he explained it. What difference does it really make if you just tap on the door at 3:00 am, and then break in the door, or just omit the tapping?
It is not really done. An open warrant is illegal. A warrant must identify the person to be arrested or the property to be searched and the evidence to be seized. It must do so very specifically so there is no possibility of confusion. For example, a search warrant must have the address to be searched and a physical description of the building/property. It usually has the legal description of the land also.By the way, he claimed he carried an open warrant around in his jacket. How is this done? I did not see it, but I believe him. He was a fed, in charge of many agents, covering a large portion of Texas.
Also, a search warrant must be served within a specific period of time. In Texas, for state warrants, that time is three days not including the day signed and the day returned. I don't know the federal rules on this but I know they are there.
He could have an open warrant but all it means is that it is the blank form the warrant application is printed on. It must be filled out and then signed by a judge to do any good.
