The Germans are known for probably the best idea humanity has ever come up with, and unfortunately, also one of the worst. This decidedly lies betwixt beer and Hitler, but is not in the realm of good ideas, if you ask me:
Germany may require gun owners to lock weapons in safes that can only be accessed with a fingerprint, as the country considers tightening firearms laws after last month’s school shooting, a government minister said.
That sounds all well and good until you slice your finger open cleaning your gun for a match the next day, and then can’t get into your safe in the morning because you marred your fingerprint. It also makes you susceptible to problems like this, which are common to a lot of electronic locks. There are also ways to defeat thumbprint scanners, and electronic locks, if you’re clever. In the case of many electronic locks, you don’t even have to be that clever.
Personally, I don’t think you can beat the old fashioned dial combination lock for both security and reliability. Properly taken care of, they will last a long time. Incidents like what happened in Germany are exceedingly rare. Thieves breaking into houses to steal guns are a lot more common. I think it would be short sighted for the German Government to mandate a type of lock that is easier for thieves to defeat, in order to prevent something much more rare.
