I'll guess that today's incidents will be the lead item on UK national news broadcasts for between 4-7 days. It'll provide politicians and a compliant corporate media with numerous opportunities to use their favourite words to instil fear, so be prepared to hear or read terror, terrorists and threat an awful lot. Maximum publicity is what the headers who commit such acts want more than anything, and the same talking heads always eagerly oblige instead of doing the opposite.

They wittingly do so because they know the citizenry will timidly accept fewer freedoms and personal privacy for they mistakenly believe they will be safer by the state recording their internet browsing history, etc.
