Hello there @Adamaris80
Some of the tactics that the police use to stop street racing are
Unmarked cars (cars that have their lights inside the car)
Street surveillance (mostly on long, straight and empty streets)
Checkpoints
and many more
Lemme know if there is anything else I can help with
I hope I helped

By French men of noble birth called troubadours and trouvères.The troubadours and trouvères were medieval musical composers. Their heritage is immense, existing today in a huge number generally medieval original copies that contain a great many ballads and several tunes to a great extent credited to singular troubadours and trouvères.</span>
I think that what Mandela means when he speaks of nation building is creating a world where everyone is equal and has rights. I think this because we know that there was a huge racial injustice at the time and Mandela was fighting for black rights. He also used the word reconciliation which means making a view or belief compatible with another or the restoration of friendly relations.
I hope this helped.
