UK Counter Terrorism Policing chief Laurence Taylor suggests the RAF Fairford suspects were released on bail as part of a tactical move by investigators to collect more evidence, which he says was successful “We know that decisions made during our investigations can sometimes appear illogical to those on the outside, but I want to make it very clear, that there will always be good reason, or rationale behind them. We will always ensure that, should we identify any ongoing threat, we will manage that as part of the investigation. “Like our adversaries, our tactics vary – and may not always be obvious. “In this case, this decision-making has led to swifter progress, better evidence and ultimately us securing the charges I have announced today. “In sensitive investigations like this, it can take time to convert intelligence, into evidence and that is what scores of my officers and staff have been doing over the last few weeks.”
