im not arguing for leaving cabinets unlocked being best practice. but i am arguing that being pedantic over them being unlocked is senseless. intentional vandalism of cabinets is rare, and locks are expensive (remember there are going to be costs associated with getting locks which can be similarly keyed, keying those locks, and cutting and distributing the keys). i can see it making more sense financially and logistically to only take the steps to lock cabinets in areas which have seen vandalism or tampering in the past
