While I certainly agree it’s best not to leave a mess, this could’ve been mitigated by simply having some trash cans available.
Public works used to provide this simple service, but ultimately has adopted the “take it with you” approach which allows the government to reduce it’s expenditures while simultaneously NOT reducing taxes.
Believe it or not, it is actually possible to make littering illegal AND have trash cans maintained by civil employees.
Depending upon location and laws it may could be possible to
use incarcerated people as clean up crews. Some would like it
being out of the cell and seeing a little of the country side. jmo
