A disturbing trend is afoot. In the past couple of months, in two countries, governments have relied on broadly-worded terrorism laws to put down social protests.

Political demonstrators in El Salvador and London have found police deploying a new weapon against them: laws designed to prevent and punish terrorism. In the town of Suchitoto, El Salvador, during a mass demonstration in early July against a water decentralization plan, fourteen protesters were arrested and charged with terrorism.

At London's Heathrow Airport this week, police have been relying on stop-and-search powers contained in a recent terrorism law to control a huge demonstration against global warming. A government document made public last Saturday warned that police would employ their counterterrorism powers to deal "robustly" with any illegal protests.

The demonstrators in El Salvador threw rocks at police and blocked roads, and some minority of participants in the ongoing Heathrow protest may also break the law. But the police already have plenty of legal authority to arrest demonstrators who disrupt flight schedules or damage property; their use of counterterrorism legislation is sheer opportunism.

Political protesters are not terrorists, as police and prosecutors well know. Yet it seems that the broad authorities granted under recent counterterrorism laws are too tempting to resist. Why would state officials respect normal criminal law rules when they can instead employ laws that offer sweeping powers, few procedural safeguards, and harsh penalties?

Conduct "Genuinely of a Terrorist Nature"

Both the British and Salvadoran counterterrorism laws are written in broad language that invites police and prosecutorial misuse. In this respect, unfortunately, they are not all that different from many other countries' counterterrorism legislation. More than 50 governments have passed counterterrorism laws in the past six years -- many of them poorly written, filled with open-ended language, and vulnerable to misuse.

The UN counterterrorism expert recently discussed the question of defining conduct that is "genuinely of a terrorist nature." He explained that the concept of terrorism should be understood to include only those acts committed "with the intention of causing death or serious bodily injury, or the taking of hostages," and "for the purpose of provoking a state of terror, intimidating a population, or compelling a government or international organization to do or abstain from doing any act."

"That an act is criminal," he emphasized, "does not, by itself, make it a terrorist act."

Few counterterrorism laws are as narrowly drawn as he and other experts recommend. Indeed, some of these laws are so broad that they easily cover political protests. They tend to cover a set of acts -- not necessarily violent acts -- requiring only that the acts be carried out for an enumerated, "terrorist" purpose.

Reading the terms of these laws, there is good reason to fear that acts of political dissent could wrongly be deemed terrorist in a number of countries. In Azerbaijan, for example, acts that inflict "significant damage to property," or (an interesting catch-all category) cause "other socially dangerous consequences," can be prosecuted as terrorist, as long as they are carried out with the goal of requiring state authorities to comply with the perpetrator's demands. Other countries' definitions are similarly broad.

Since social protest is almost always meant as a form of political pressure -- that is, a means of compelling state authorities to change their policies -- the purpose requirement of such counterterrorism laws will almost always be met. And so the possibility of arbitrary enforcement of such laws is very real.

Placards Not Bombs

With fears of terrorism high, many governments now have tough counterterrorism laws at their disposal. But while the extraordinary powers granted to police and other state authorities under these laws are publicly defended by reference to the threat of terrorism, some of the actual conduct they apply to has little connection to the problem.

Governments apparently need to be reminded: political protesters are not terrorists. Rock-throwers are not suicide attackers. People carrying placards are not people carrying bombs.
