Karachi Watch is a glance-tool for the city — colored zones tell you how risky an area tends to be right now, based on public reporting and community input.
This won't stop a snatching. It's a small tool to help you plan around Karachi's worst hours — the ride home, the late errand, the walk from the parking lot. Use it with your own judgment, and please report what you see. The map gets better every time someone does.
