In October 2014, we visited former President George H.W. Bush's Houston residence in response to a complaint alleging alarms were inoperable. During our visit, we identified issues with the alarm system at the residence. During the 13 months that an alarm was inoperable, the Secret Service protective detail created a roving post to secure the residence and no security breach occurred. However, we found problems with identifying, reporting, and tracking alarm system malfunctions, and with repairing and replacing alarm systems. Because these issues may be affecting other residences, we are bringing them to your attention.
