Last week a group of people staged a protest outside Fluent's Sheffield, UK offices. Citing Fluent's "use of software for airflow modelling of missiles", the group was more likely trying to gain pubilicity for themselves by staging an early protest against this week's DSEi defense conference in London, of which Fluent is an exhibitor.
According to this report, four people barricaded a revolving door, two others locked themselves to the door using bicycle locks, and others hung banners including "Fluent Deal in Death" on the main entrance.
Police failed to stop the action because "work was not stopped" (a backdoor remained open), however, they are fortunate that an emergency did not occur in the building with the main entrance blocked.
Civil action has its place, but it is clear that this group is misguided -- another website reported the action as "Sheffield Arms Traders Targeted".
