mmm. why? delay of court,prosecuting the victim, destructing the jury, .. a few fav tricks, delay (and threat by gov workers) being the most used.
telling an all day sucker "well there's no law in the books we'll have to write one" is a common trick and used heavily from 1800's till now. it was illegal to bullshit like that.
the issue at law likely wasn't about smell or rumor (maybe).
what if you bought a house and found out police had "permanent access" to the house based on the fact it was the scene of a past crime currently under investigation ? or maybe that there could be a future lien situation due to other laws ? AHA! it maight not be abut ghosts

good you should start from the beginning of legal history at least 2000 yrs ago, not the hinds end of "ms word changes" of 2013. the first written laws forward. not what politicians recent rantings and edits which legally are illegal to be in law books (but ok in regulation books)
