New-ish tactics used by the police force are a great way to use force to contain people without leaving evidence of what they did.

From the Guardian’s article on the use of the sonic cannon:

Sonic weapons or long-range acoustic devices have been used by the US military overseas, notably against Somali pirates and Iraqi insurgents.

But US security forces turned the piercing sound on their own citizens yesterday to widespread outrage. Pittsburgh officials told the New York Times that it was the first time “sound cannon” had been used publicly.

This study investigated biased message processing of political satire in The Colbert Report and the influence of political ideology on perceptions of Stephen Colbert. Results indicate that political ideology influences biased processing of ambiguous political messages and source in late-night comedy. Using data from an experiment (N = 332), we found that individual-level political ideology significantly predicted perceptions of Colbert’s political ideology. Additionally, there was no significant difference between the groups in thinking Colbert was funny, but conservatives were more likely to report that Colbert only pretends to be joking and genuinely meant what he said while liberals were more likely to report that Colbert used satire and was not serious when offering political statements. Conservatism also significantly predicted perceptions that Colbert disliked liberalism. Finally, a post hoc analysis revealed that perceptions of Colbert’s political opinions fully mediated the relationship between political ideology and individual-level opinion.
