You raise a very valid and important point about police involvement, and how Airbnb's fractious and combative relationship with law enforcement agencies around the world has caused hosts to be put at even greater risk, because they're often too reluctant to call the police, in case it gets them shut down.
The police in many jurisdictions are amongst the strongest, most vocal and most powerful objectors to Airbnb activity being permitted to continue in their cities, due to the massive drains on their time, manpower and resources in dealing with endless Airbnb callouts (the majority of which, turn out to be civil matters anyway. (There are numerous reports of police in many regions now refusing to attend Airbnb callouts at all, except in dire emergencies, because they've simply had enough of being used as if they were Airbnb's private security firm)
And despite their CX agents routinely advising hosts to "Call the cops", for every little thing, Airbnb is not so quick to cooperate with the police when they're the ones seeking assistance of information from the company, even in serious or time-sensitive cases. Law enforcement agencies are forced to jump through a serious of laborious hoops to request information from Airbnb, and are often met with stonewalling and intransigence, rather than assistance.
Apart from having to provide reams of documentation for the most basic pieces of information, if the police are chasing someone in particular (say for example, a suspected murderer using a series of Airbnb's as safe houses), Airbnb also insists that the officers provide them with a Non-Disclosure Order, otherwise their policy is to inform the guest (criminal) that the cops are trying to track him/her down. Then they'll carefully scrutinise the NDO for "legal deficiencies", before deciding whether or not to honour it. As the clock ticks down...
"Where Airbnb identifies a legal deficiency in a non-disclosure order, Airbnb’s practice is to inform the requesting law enforcement agent about the deficiency and indicate what the appropriate process would be"
From the latest stats available (Jan 1 - June 30, 2018), 1368 law enforcement requests were submitted to Airbnb for user information globally, yet in only 305 of those cases, "at least some account information was disclosed"
So all this has inevitably resulted in a preposterous - and extremely dangerous - situation where the relationship between Airbnb and various law enforcement agencies has deteriorated to such an extent, that not only can hosts not rely on Airbnb to back them up in times of crisis, they can't (or are too scared to) call on the police for back-up either.
