MP’s also hold ‘surgeries’ in your local area where you can meet them face to face to raise your concerns. This is a great way to build a relationship with your MP, and also to hold them to account when they are not doing what they are paid to do.

You can take forward your complaint on the discriminatory nature of Schedule 7 Stops by observing others that are stopped, or not, around you and the questions that you are asked.
The conduct of the officers can also be held to account as they need to identify themselves, tell you under what law you are being stopped and what your rights are. They also have a duty to be polite and fair-natured.
