Until a couple of years ago, parcel services dropping the package at the entrance wasn´t a thing over here, they rather had 3 tries to deliver (which doesn´t make much sense, as you are likely to be e.g. at work at the same daytime in these 3 days), after which you could fetch it from the post office. Now you only get 1 try (depends on their route if you are lucky to be at home when they come), but you could give consent in advance (online) to put it somewhere, alternatively a neighbour signs for reception and you get a written notice which one has it.
A saying here goes: It´s the opportunity that creates the thieves.
If you give consent to have it dropped at the front porch you more or less take responsibility - a theft is still a theft, but it is not the parcel service´s liability then. It might even be considered careless behavior and you will pay for it - might explain the police officers reaction to it. When all security and liability is replaced by convenience, it might be seen as the majority of the cause for such crimes.
When looking at these people... they seem to just drive around and collect it as if it was their right. Of course this means there are low moral standards, low security, "the insurance will pay for it", "making couple of hundred dollars per hour off stupid, lazy people" and such reasoning. However, last thing you want is the law enforcement protecting or ignoring the criminals because the only existing evidence was tampered with.
I mean the video was funny, relatively harmless and interesting to watch, but building trap devices is of course a double edged sword in what they are used for and why. There is no guarantee that such a device is not encountered by underaged, stupid kids (in countries in which kids are actually allowed to go outside alone), animals, drunk people and such. It might hit the wrong target.
