Because everything about his life including clearances held, offices worked, as well as physical descriptions of he and his family members has been compromised. if you do not think that places him at a higher risk then I dont know what will. Even the MSP is now agreeing with the statement.
I partially agree with you assessment that someone in the military may be at higher risk, overall.
However, most people are looking at the entirety of the situation(ccw) under the pretense of fear of common criminals. You are MUCH more likely to be mugged, robbed, attacked, etc by some random thug than you are to have a secret terrorist op looking to take you out based off of info gleaned from the opm hack or some isis source.
