Bringing an electric gun in the streets (Belgium)
<p>Is it permissible to bring an electric gun in a hoster just in case of self-defense? Is there a need of a special written permission by a police department or a weapon center or by a court? What are the bureaucratic steps to entertain for this? 
Even if it is GENERALLY illegal, can I ask for a specific permission and get it through a hard bureaucratic process?</p>

<p>Jurisdiction: Belgium</p>

<p>This answer assumes that with the term <strong>electric gun</strong> that you mean a <a href="https://en.wikipedia.org/wiki/Electroshock_weapon#United_Kingdom" rel="noreferrer">electric gun</a>, which is also called a <strong>Taser</strong>. </p>

<p>With the exception of <strong>Austria</strong>, such devices are generally forbidden. </p>

<p>In many, the police were allowed to use them, but that is now often restricted. </p>

<p>Therefore for Belgium, you would need a permit issued against the <strong>Weapons Act 2006</strong>. </p>

<p>The chances for such a permit, to also be carried openly in a holster, for the general purpose of self defense is <strong>very unlikely</strong></p>

<ul>
<li>such permits are mostly only granted when the applicant is deemed by the authorities to be in great danger</li>
</ul>
