Really? The government shouldn't have a right to detain people who are a potential flight risk? They shouldn't have the right to raid an office in search of evidence which may be potentially destroyed? This all seems to be part of a basic allegation.
On the flip side we can look at issues like the "terrorist" attack in Sydney last week, you know the one committed by a guy who was out on bail awaiting trial for 50 counts of sexual assault and accessory to murder?
Or just look at the countless cases of destroyed evidence which appear in the news every day.
I think the opposite to you. On an allegation any reasonable steps need to be taken to ensure they are investigated. People shouldn't be allowed to leave the country, offices should be raided. Otherwise it is simply too easy to avoid prosecution.
