I'm not generally a Popular Mechanics reader unless I'm cooling my heels and it is in the magazine rack. So I don't have any feel for what, if any, political leanings they have (they always seem pretty straight down the line about whatever they are reporting on to me).
Anyway, (ht: Instapundit) they are having a look at the congressional report about Katrina and finding it less than sterling. Congressional Report On Katrina: First Look.
Read it for yourself but the criticisms seem valid enough. The question is, of course, why can't a congressional committee with the resources of the US federal government, do a report that survives scrutiny by Popular Mechanics. So far the most informative MSM reports I've seen about Katrina have been in Motor Trend and Popular Mechanics.
