Same goes for CNN, which is generally attroctious in talking about specific military hardware. This stuff is complicated, and your average journalist doesn't know any more about it then your average civilian.
Secondly, it doesn't contradict me. Time limited devices are less then 24 hours. These were permitted under every regulation, and nothing has changed with this policy. What this policy allows is devices up to 30 days. This is exactly what you quoted.
The reason why the shorter devices are more dangerous should be obvious, they are expected to take care of themselves. If you emplace mines for 24 hours, they are "Fire and forget". You emplace them, and 24 hours (Or less, depending how you set them) later they self destruct. If you emplace a mine for 30 days, you are responsible for it for 30 days. The problem comes from dud rates, like I mentioned. Basically, the self destruct device on 5-10% of the mines will probably fail, leaving active, but malfunctioning devices still in the area. This can cause casualties much later. They are still less dangerous then the WWII era mines the soviets left in Afghanistan, but they are definitely a risk to civilians.
Now the 30 day ones are very different. They only self destruct 30 days after being abandoned. You can keep renewing the 30 days indefinitely as long as you remain in contact with the mine (Through a wire usually). So we don't intend to actually use the 30 day feature, it is just a failsafe in case we have to leave in a hurry. What we actually do is physically demine the area before we leave. I did this on three different bases in Afghanistan with exactly this type of mine. Dud rates aren't a big issue, because you are physically removing every mine before you do. These would be a risk to civilians if they were deployed in the field, but like I mentioned, they are really only used in belts around the fencing protecting bases, inside a double fenced perimeter (So inside the first fence, but still outside the final perimeter fence). They only kill people that have already crossed the first fence of a secure military facility, and it you crossed that much Concertina Wire, you should know what you are getting into.
