Mr President, they did NOT miss any signals. Obama was President when they received the first tip. Lynch and Comey ran the Justice Dept at the behest of Obama and Hillary.
This first tip was their in to groom this kid and keep him on the psychotropic drugs to help them in their quest to Disarm Americans. The best way to stir emotions is always a School Shooting.
When they got the Second Tip, they knew time was running out, so they [put their plan in to High Gear and before too many people started asking questions about these tips and non investigations regarding them, they put their Plan in to Action.
As you can see, it worked and the discussion is now about Disarming American Citizens.
I think the discussion be whether or not he is mentally fit to be found guilty and whether or death penalty is suitable.
I know Tim McVeigh did use seemingly endless appeals and was put to death 6 years after his crime.
