Terrorism Bill

Clause 21 states:"““The glorification of any conduct is unlawful for the purposes of subsection (5A) if there are persons who may become aware of it who could reasonably be expected to infer that what is being glorified, is being glorified as . . . conduct that should be emulated””." If one celebrates the life of Michael Collins, it will be to some people a celebration of a historical phenomenon, but for others it might be a live issue because they believe that they are emulating Michael Collins by killing people in Northern Ireland. How does one make the distinction? The phrasing of clause 21 does not succeed in making that distinction, and I could cite countless other examples.
