Yeah, people on here are talking like their front door is Fort Knox. For most it is not, and as mentioned in other comments, a window is much easier to get through.
The primary risk is in thieves entering your home without leaving any traces.
Breaking through a door or windows requires a certain amount of risk and commitment. If a malicious hacker gets remote access to a smart lock the risk is effectively zero.

This is an extremely worrisome statement. Is there any precedent for this type of coercion from the FBI to businesses who have access to a home? My justice-sense is tingling to think that the FBI could get into my home by coercing any party that I give access (hypothetical maids, pool guy, cat sitter, etc)
The cam verifies the delivery person won't come further than a step in, not much to snoop there. Anything further would be easier and less noticed with a locksmith.
