When arrested, aggressive criminal defence will extract all the weak links in the crown’s case. Weak links can lead to the doubt you must raise to be acquited of the charges against you.
Some of your fundamental rights include: that you be presumed innocent before proven guilty and that police officers cannot conduct a search or seize your belongings without a warrant, except in very limited and exceptional circumstances. You also cannot be arbitrarily detained or imprisonned.
If you are arrested or detained, you must be promptly given the reason thereof. You must also be informed and be given the right to speak to an attorney.
