It's true that the average random person doesn't need a lock by Abloy/EVVA/etc. just because it's (as close as possible to)unpickable, but I would always avoid bumpable locks as well as ones that are (more)vulnerable to destructive attacks, two categories which include quite a lot of 'high security' locks including UL 437 rated ones. Bumping is still rarer than breaking a window, crowbarring a weak door frame, or kicking at the spot of a weak lock, but is definitely increasing in popularity as it's significantly less obtrusive and doesn't leave visible damage that may alert passers by while the crime is still in progress. Myself, when I am able to own my own house, I am definitely fitting upgraded (unbumpable) locks as part of basic diligence with regards to security, along with fixing any easily breakable windows. It's also worth noting that windows can always be reinforced/refitted with laminated glass or even protective films that provide enough protection that the random opportunistic crackhead will probably give up when it doesn't break straight away so as not to get caught. Burglaries that take longer than 30 seconds or so to get in will often be aborted because of the risk of getting caught, especially when there are so many houses with no or insufficient alarms, windows that can server as an easy entry point without a motion sensor behind them, and weak locks that can easily be bumped/pulled[1]. If you have big breakable windows, always invest in a good alarm with motion and/or glass-break sensors though. [1]Pulling/snapping is gradually becoming the new bumping - some lock designs are physically weak enough that they can be either broken inside the door or physically pulled out with hand tools.
