The only people impacted are the custodial staff who are left to clean-up the mess and depending on the type of vandalism will require them to deal with 'toxic substances' like paint which will expose the workers to 'toxic solvents'.
In this case, it's only water-based dyes but in the past they have used real blood, urine, and other wastes and chemicals.
These 'activists' never seem concerned about the people who will have to deal with their vandalism.
