I'm sure and yes. I just read the link provided and this bit proves we are far too soft!
29 April 2013: Pavlo Lapshyn attacks. Lapshyn, a Ukrainian student and right-wing extremist, stabbed Mohammed Saleem, a Birmingham resident to death. He later admitted to police that he wished to start a "race war".[28] Lapshyn later detonated a home-made bomb outside a mosque in Walsall on 21 June. 150 homes were evacuated but no person was injured.[28] On 28 May Lapshyn detonated a second home-made bomb near a mosque in Wolverhampton, and attacked a mosque in Tipton with an improvised explosive device containing nails on 12 July. Friday prayers were delayed that day, and so his intended victims were still inside. Laphsyn was later sentenced to serve a minimum of 40 years.[29][30][31]
So he stabs someone to death in April, yet is still at large in May and June to commit more attacks. Surely after the first stabbing he should have been locked up.
