I should not be disappointed or upset by this. I should be happy that a sport is willing to take hit after hit in pursuit of some sort of honesty. However, I can't avoid a feeling of dismay as I gradually begin to suspect that every elite athlete in the world is doping.
At least track & field is not involved in Operation Puerto, so far as we know. Although if you read the linked press release carefully, Spain’s Guardia Civil is not investigating any athletes outside of cycling. They may, in fact, be involved.
