UK releases al-Qaeda operatives who plotted to bomb shopping centers

What's the point? Have they been rehabilitated? Have they not, in planning to bomb shopping malls in the name of Allah, committed Sedition? Should they not have been jailed for life, or have been shipped out to the Sharia-state of their choice?

None of the men were charged with any crime but the government launched
an attempt to have the men deported. ?THIS OK?Their lawyers are objecting to the
deportation orders, arguing that they should be freed to continue their
