marvel - Is there an in-universe explanation why nobody traced Spider-Man via his purchase of Oscorp Biocable?

Per the Wikipedia article on Spider-Man's webcasters, in the original comic book Peter Parker develops the webcasters on his own as "an extremely intelligent and creative" scientist. Per the same site this is further explained in 1994's Spider-Man: The Animated Series. In it Parker explains that when he became Spider-Man, he also became subconsciously aware that a combination of certain enzymes would create a strong, sticky fluid reminiscent of a spider's webbing. He then built web-shooters as in the comics.

However, in The Amazing Spider-Man while we see Andrew Garfield as Peter Parker assembling his web-shooters, the Oscorp Biocable box on the table (and accompanying voiceover description) insinuates his source of webbing is from Oscorp. It never shows any other location/place/source that Peter might make his own webbing. If that is the case, why wouldn't anyone think to try and trace purchases of the webbing to identify Spider-Man? Also, even if Peter did happen to start making his own webbing, wouldn't investigators initially assume it MIGHT be Oscorp bio-cable and attempt to trace at least his first purchase?

If perhaps Peter didn't purchase the first box, wouldn't the police still make an effort to trace who might have had access to obtain biocable? E.g. if Peter obtained it through his internship contacts while at Oscorp, he would likely show up on a leads list of suspects. A routine background check asking about him at school would quickly turn up the fact that he had behaving oddly and demonstrating superior physical skills.

In fact, Dennis Leary as Captain George Stacy alludes to the fact that Spider-Man "makes mistakes". He is sloppy and leaves clues. I would think leaving the biocable webbing around at his activity sites would be a pretty good lead on which to follow-up.

Is there something in the movie I might have missed on this that someone can help point out to me?

Answer

I enjoyed the Amazing Spider-Man, but it is not exactly flawless. This question identifies quite a major hole in the film's logic. When I re-watched it I realised that Peter Parker just has the box of Oscorp "biocable" in his bedroom, with no prior explanation of how he got it. I began to wonder ...

"Wait, how could he afford something like that? It can't be cheap. And why would any multi-million (or -billion) dollar corporation sell it to a teenaged kid? Wouldn't he have to send in some sort of evidence or ID to prove that he works for another corporation/research facility capable of correctly and legally utilizing it? He's just a friend of Doctor Connors, how does that grant him access to this stuff? Wait a minute ... did he steal it? Did he obtain this scientific miracle illegally? Or did Curt Connors put in a request for the biocable because Peter had asked him for a favor? Wouldn't Connors be a little suspicious of such a request if this was the case?"

We just don't know! Peter Parker just - has it! Now, maybe I'm mistaken and missed something, but I cannot remember a single mention of how Peter Parker got his hands on the box of webbing. So, really, this is a question that can't be answered because the questioner, Beichst, is completely right. If a man in red and blue spandex appeared on the news, swinging from building to building using spider-silk, and a certain world-renowned R&D company had been known to produce synthetic spider-silk, would it be that hard for the police to put two and two together and figure out who was purchasing this material? It seems to me that Beichst asked this question to point out a hole in the film's logic - and he succeeded spectacularly! There is no rationalizing it - it doesn't make sense that Spider-Man's secret identity could have remained secret.
