The keys to open bus stops are now available from my website shop, if you use them to put up a black lives matter poster I'll refund the cost of the pack - just email me a photo. You can paint or draw on the back of the original posters you find in the bus stops. Every poster you put up gives you another poster to adjust. Let's cover the streets.
If you can afford to please donate to US protester bail funds and write to your MP! Let's not pretend that racist police violence is just an American problem.
