Nothing has really changed when it comes to the power of arrest held by the police.

For the vast majority of cases this has only ever required a reasonable suspicion.

What has changed is how the information that someone has been arrested is so easily disseminated.

In the past news of an individuals arrest was often unknown, even amongst their family.

Which way is better is open to debate but the more "open" way we currently have means, in my opinion, that far more care needs to be taken regarding the grounds for any arrests.
