Show how long a warning has been posted
Many times when you see a police icon, they may already be gone when you get there. It would be nice if you could press the icon and it would read out how long the icon has been up. That way, you have an idea as to if they would still be there or not.
For instance, if it said 30 minutes, chances are it’s gone. But if it said 5 minutes, changes are it’s still there
