Only 10% of serious cycling injuries in Ireland were recorded by Gardai
The Bedford Report for the HSE in 2011 showed that only approximately 10% of serious injuries (with hospital admission to a bed) incurred by cyclists in road traffic collisions were recorded by Gardai. If a cyclist is knocked off his/her bike from impact with a motorised vehicle that is a potential criminal offence if serious injury results. Cyclists expect all such RTCs to be properly and fully investigated and recorded with appropriate follow-up. That clearly is not happening at present. Acute hospitals need to document all admission cases arising from cyclist RTCs and inform the Gardai of them.

Obfuscatory pie-chart from Garda penalty-points corruption report
"Twitter / gavinsblog: For sake of clarity here is helpful pie chart of the 95.4% of fixed charge notices not terminated #missingthepoint"

Paging Edward Tufte: classic example of an obfuscatory pie-chart, diagramming the wrong thing misleadingly. By presenting it like this, it appears that the 95.4% of cases where fixed charge notices were issued by the guards are relevant to the discussion of the other classes; in reality, that means that 4.6% of cases, 37,000 cases, were terminated, some for good reasons, others for not, and it's the difference between those two classes that are relevant.

In my opinion, 2 separate pie charts would be better; one to show the dismissed-versus-undismissed count (which IMO could have been omitted entirely), and one to show the good-vs-not-so-good termination reason counts (which is the meat of the issue).
