Technically correct since ULA was formed in 2006 there has been one partial failure (primary mission not achieved), one partial failure which was dynamically compensated to achieve orbit. Going back further in their rocket programs' histories, there was that little incident in 1997...
Atlas V: "The first Atlas V was launched on August 21, 2002, and all subsequent launches have been successful except for the 2007 anomaly.... The only anomalous event in the use of the Atlas V launch system occurred on June 15, 2007, when the engine in the Centaur upper stage of an Atlas V shut down early, leaving its payload – a pair of NRO L-30 ocean surveillance satellites – in a lower than intended orbit. The cause of the anomaly was traced to a leaky valve, which allowed fuel to leak during the coast between the first and second burns. The resulting lack of fuel caused the second burn to terminate 4 seconds early. Replacing the valve led to a delay in the next Atlas V launch."
Delta IV: "An anomalous event with the Delta IV launch system occurred October 4, 2012, when a leak developed above the narrow throat portion of the thrust chamber in the RL10B-2 engine within the Delta's upper stage. The payload's small mass and the upper stage's excess fuel load coupled with the fault tolerant guidance software - which recalculated and fired the engine longer than planned - resulted in the satellite being placed into the intended orbit."
Delta II: "In total, the Delta II family has launched 152 times. Its only unsuccessful launches have been Koreasat-1 in 1995, a partial failure caused by one booster not separating from the first stage, which resulted in the satellite being placed in a lower than intended orbit. The second failure on January 17, 1997 (launch of a military GPS satellite) ended spectacularly when the booster exploded only 13 seconds after liftoff due to a ruptured SRM casing that accidentally tripped the range safety destruct package. Flaming debris rained down onto LC-17A in a multimillion dollar fireworks display. No one was injured, and the launch pad itself was not seriously damaged, though several cars were destroyed and a few buildings were damaged. The disaster was only the third total failure of a Delta in the past 20 years and produced uncomfortable reminders of the 1986 Titan 34D accident which also exploded just above the pad from an SRM malfunction."

Would you rather fight a horse-sized duck or a hundred duck-sized horses?

From my perspective, it was an awful lot like living in 1960, 1970, 1980, 2000, and 2010. Only different.

A decade or so ago when LoJock was introduced, I recall reading that it changed the game for professional chop shops. The trackers in even a small percentage of cars substantially increased the risk. Car theft gangs had to build in a several day cooling off time when the car sat parked somewhere.
Is it possible the gangs are using children as thieves because they won't serve long sentences or carry permanent records?
