Jail rock-thrower

Re: ‘Driver ad­mits rock-thrower at­tack’ (20/3) when a po­lice pros­e­cu­tor has called for a jail term af­ter things got phys­i­cal dur­ing the ap­pre­hen­sion of an of­fender af­ter a rock at­tack upon a mov­ing car.

It’s clear the le­gal sys­tem is out of touch with the real world and has no idea of the ki­netic energy forces at play with ve­hi­cles mov­ing at speed.

Most peo­ple re­mem­ber the on-field death of crick­eter Phillip Hughes by a ball weigh­ing 156g trav­el­ling at 150km/h with an im­pact force of 135 joules.

The .38 cal­i­bre po­lice re­volver fires a 9.53g bul­let at 270m/s with an im­pact force of 347 joules and is cer­tainly deadly.

A wo­man soft­ball pitcher can throw a large ball un­der­arm at 124km/h, so a con­ser­va­tive speed for a rock-thrower.

A car trav­el­ling at 80km/h col­lides with a 575g bot­tle trav­el­ling at 124km/h. The ki­netic energy is 923 joules, a force greater than two pis­tol bul­lets com­bined.

Jail time is cer­tainly ap­pro­pri­ate in this case for the rock thrower, not the per­son whose ac­tions stopped the at­tack on in­no­cent mo­torists.

The next car to be hit could have been an­other sense­less fa­tal­ity.
