And about the news links, since we are talking about environmental and animal rights protest groups, I would say the terrorism here comes from the police. Making a baby for better undercover credibility is very low and in no relationship to the threat of the quite harmles activists. But this is a good indicator, of how willing the secret forces are, when it comes to real terrorists. There were years of investigations into the NSU in germany (https://en.wikipedia.org/wiki/National_Socialist_Underground) for example and how close exactly the double agents were to the terrorists and how much involved.
