Lin Miao's work on this was actually pretty rough, so rough it didn't seem like something he would do.
There are actually quite a few military technology personnel inside the White House. As long as a post-mortem is conducted, and confirmed with superiors, it's easy to find out that this group of attackers was just disguised in military technology combat uniforms.
Besides, there was no way the attackers could escape alive. After all, this is Washington, heavily guarded. Just three minutes after the attack happened, the first reinforcements had already arrived.
If it weren't for the European Community trying every means to eliminate Lin Miao by using covert lines, revealing these attackers in Washington for Lin Miao to deal with before settling them down, he would not have had a chance to get these people to the front door of the White House.
