well, I agree partially that dragging army is wrong because of one wife of a one col , but still the comparison is wrong .. This lady has done a wrong thing, the lawyers shows in your picture is from a protest and not just some protest but one that turned violent , which happen all the time .. So Police and public property burned by angry mobs and protesters all the time, you can see it in USA , UK and even France and Germany .
What the lady did was abusing a officer who is doing his duty, just because she is a wife of a senior officer doesn't give her right to abuse a junior officer who is doing his duty . Now one might say her husband didn't do anything but point is when a soldier do something wrong or fails his commanding officer have to face consequences ( sometimes ) . Her Husband should have understand the nature and personality of his wife and warned her about misusing his position anywhere .
I've one Cousin in Army ( brig lvl ) and he give me his card around 7-9 months before he retired that too when i was going for Interview in Islamabad and I have to stay in Army mess officer at Pindi . She is a wife of a dedicated army officer she should know better that Army is there to serve , not Rule .
