America is a big place. But in some parts, they put the murder suspect under surveillance for at least a couple of days while they gather more evidence. [
link] (especially when all they have to go on is a possible sneaker print)
That is an interesting link. I do not see it is comparable for a number of reasons but I am open to correction.
In the case cited there does not appear to be any evidence tying this man to the murder: he worked at the place the victim worked and he went home early that day, saying he was unwell. He had some minor scratches on his arm. It may be that there is other evidence tying him to the crime, but it is not reported. In addition there is apparently another man who had also worked in the same place and allegedly exposed himself to her. I wonder if they placed him under surveillance too. Or if they had a whole lot of folk under watch?
In contrast, in the case of Patrick Lumumba they had evidence from RS that Knox was not where she said she was when the murder was committed: and they had his statement that what he said originally was a lot of rubbish which he said because he believed what Knox had told him and did not see the inconsistencies in her account. They had reason to believe she left the house: and they had reason to believe that she had arranged to meet someone, because of the way she worded her text. Knox did not explain that misunderstanding but instead she accused Lumumba directly of killing Meredith Kercher. An accusation she repeated when she insisted on making a further statement in the course of the night.
I believe that in order to arrest someone in the USA the police must show something called "probable cause" to someone (presumably a judge or a prosecutor). In the NYPD case you cited I do not see anything which would qualify. But then the question arises: would a direct accusation from someone who claimed to have been present; coupled with a complete lack of evidence showing her to have been anywhere else; a statement from a third party which indicated her earlier statements were lies; and a text message which indicated she had arranged to meet this person that night, constitute "probable cause"? I honestly don't know how that works in the states but I remain very surprised if that is not enough for the police to detain someone at least for questioning, and while awaiting the forensic findings from the crime scene.
If it is not then it seems really quite dangerous to me. The person so accused could flee; or kill again; or intimidate witnesses; or whatever.
In this country, if the police did not detain someone in those circumstances and the person committed another crime or was able to get away then the police would be pilloried. I can see the headlines about how their failure to act let a murderer kill again: and I know there are just such headlines in the USA as well because it was mentioned in a thread. Sometimes, when they have no legal power to act, the police just have to take those lumps:as do all public servants from time to time. But I am yet to be convinced they would be so hamstrung with these facts to present to whoever grants the right to arrest. That would be a brave official indeed: one might almost say foolhardy. Or so it seems on the surface.
I do not know what size Staten Island is, but it is my belief that the NYPD is a big police force. Not sure if that is correct. I imagine, and again I am open to correction, that it is perhaps better resourced than the police department of a small university town which has not seen a murder for years. I have looked for accounts of such surveillance in smaller towns in the USA but I have not found any. Perhaps you know of some? Maybe the size of the department does not make any difference? I think it probably would but I could easily be wrong
Another thing which occurs to me is that I have absolutely no idea what this committment of resources is actually for. In the link it seems that they were able to arrest him for a different crime entirely. I cannot see that as a very likely outcome, though. And even serial killers leave gaps between their murders, so how long are you going to watch, if the aim is prevention or to catch him in the act? Perhaps the intent is to ensure he does not flee? But if there is no evidence to detain him I cannot see how you can legally restrict his movements, so that does not seem to work. So what is this actually for?
I assume that to place a citizen under such surveillance must also be authorised by someone? Perhaps it is an operational matter for the police themselves? I sincerely hope not, but it may be just a resourcing decision for the police chief. How that does not open the way for a suit for harrassment or intimidation is not obvious to me. And from the link it seems that he and the woman were aware of the surveillance both from unmarked police cars and from the media. WTF is all that about? Is it ok to tip off the media that someone is potentially a suspect in a murder case and allow them to follow him about? While the police are doing the same thing? This is very strange to me.
I did notice this, though:
The attorney said he's mulling a civil lawsuit after police questioned his client for 25 hours without offering him food, water or the chance to use the facilities.
I wonder if that is why some of the americans here were so ready to accept this same claim from Knox? Perhaps it is routine in some states and so seemed plausible? It has been shown to be wholly false but even before we had evidence for that, it was wildly improbable to me. If things are done like that in some of the states that may account for the fact that she (or her family) even tried it? Just a thought
