Agreed, Keith.   But are you then prepared to detain a significant proportion of the people closely linked to that address for the 14/28/90 days in the expectation that one of them is the guilty party? In the actual case, was the most likely suspect held for the full 14 days that currently apply? If not, I don't see how extending the time limit would have made any significant difference.

Another question. Do you know why it took 14 days? Were they working on it for all fourteen, or were 12 of them wasted because they didn't have the staff levels or special equipment needed? If the latter, its a good argument for increased staff/resourcing, but not for changing the time limit.
