Perhaps if the 'Litter Police', did have brush and shovel, they could give the offender the choice, pay the fine or clean this stretch of gutter that you have desecrated.
No that wouldn't work, before they could use the brush and shovel, The Councils Health and Safety official would have to assess the stretch of the road and take them round to the council depot to kit them out with all the safety equipment required, safety boots, hi-vis' jacket, gloves etc and they would also have to go on an induction course to ensure they lifted the shovel correctly!
No Less this is not the sweeper you will use!
This is what you'll use!
Less kitted out and ready to work off his fine!
