We should not take the 'little precautions' after the attack, and let security failures on other major installments?
Security arrangements are made for such attacks. If 20 men with RPGs and suicide vests attacks you, you can NOT avoid the loss of minimize it with security alert. We will find it latter if this again was a security failure or the forces resisted the attack to maximum in initial stages. Remember, when they have explosives, the case is different than with only rifles. All they need to do is blow away one wall of the installment regardless of the number of security personnel present.
Being disappointed by some decisions of Army is quite different than being an AAA. We are under immense pressure and hence most of the 'flaws' could be understood. But there ARE some things which do require criticism, I see the flaws in Army too but I don't go to streets and yell slogans against them.
