This is a sad day for their army, not because I dislike glocks(I really like my 34), but because I like my HP even more!
In all seriousness though, I think any anti will simply twist events like these into something along the lines of "See, they are military weapons so regular people should not have them". Features, such as simple operations and maintenance, which make it attractive for large organizations, also make it attractive for self defense users. It is unfortunate that even today there are those that simply don't recognize the right to self defense.
