Tis the hot topic at the moment
People attacking babies is last months news
Presume they will be charging them under the firework laws which has a max sentence of 3 months for illegal use.
Add health & safety breach, illegal possession, public nuisance, reckless endangerment, possibly being drunk and disorderly, attempting to hide the evidence (however pointless). vandalism, breach of the peace (irony).
Of course will a custodial term actually deter the morons or make it more of a thrill for them?
