Is there any reason to detain people? Just sending them away is much faster and gives you more time, since time continues to run while the guy is escorted away. I guess that's because it's a Beta or am I missing something?
Also (since I don't want to open another thread about that) sometimes you have to scan the fingerprints of people right? Even if they match I get an error-message if I let them in, is this a bug?
