Some are questioning whether warning signs about certain aspects of Michael Piggin's behaviour were missed, after it emerged in court that the teenager had a fascination with Nazi memorabilia.
Mr Piggin, who has Asperger's Syndrome, was cleared by a jury of preparing an act of terrorism in Loughborough.
During the trial, the court also heard that he was a supporter of the English Defence League, and that police found a number of articles about the Norwegian right wing extremist, Anders Breivik, who killed 77 people in a mass shooting.
The Crown Prosecution Service have responded to a second jury clearing teenager, Michael Piggin, of plotting a Columbine-style massacre in Loughborough.
A spokesperson told ITV news Central:
We're content that we've followed a clearly established policy with regards to this case.
A teenager accused of plotting a Columbine-inspired massacre in Loughborough has been cleared by a second jury at the Old Bailey in London, after they could not come to a decision.
Michael Piggin, who is now 18, outlined in his diary plans of deadly attacks on two schools, a mosque, council offices and Loughborough University. The A-Level student wrote about arming himself with guns, bombs and knives.
But he claimed the details he wrote were a way of venting his anger, rather than serious plans.
It is the second time a jury have not been able to reach a decision, and he will not be tried again, as defendants are never tried for a third time. Mr Piggin has therefore been cleared of preparing an act of terrorism, and other terror offences.
He had admitted to possessing a knife, and also confessed to possessing parts for an improvised explosive device halfway through the trial. He will be sentenced on 13 June.

A Downing St spokesman has clarified that the new Financial Secretary, Nicky Morgan, will report directly to David Cameron on women's issues, rather than to the new Culture Secretary, Sajid Javid.
The role of minister for women and equalities has been split, with Ms Morgan taking on the women's brief and Mr Javid handling equalities.
She will report directly to the Prime Minister on women's issues. She will have an office as Minister for Women, supported by DCMS staff. But with regard to her responsibilities for women, she will report to the Prime Minister.
Sajid Javid will have the ministerial lead on equalities issues and Nicky Morgan will have the lead on women's issues.
