Ok, I used Firebug to record that requests going to the server, and what comes back.

Here is the stuff from FireBug:
Headers

Post

Response

So I wrote this code to try and do the same kind of request:
#!/usr/bin/perl

use LWP::UserAgent;
my $ua = new LWP::UserAgent;

my $string = <<END;
<?xml version="1.0" encoding="UTF-8" ?><ARCXML version="1.1">
<REQUEST>
<GET_FEATURES outputmode="xml" envelope="true" geometry="false" featur
+elimit="1000" beginrecord="1">
<LAYER id="6" /><SPATIALQUERY subfields="CCNO CRIME_DESC FROM_DATE PRE
+M_DESC LOCATION POST DISTRICT"
 where="(FROM_DATE &gt;&#061; {ts '2009-01-01 00:00:00'}) AND (FROM_DA
+TE &lt;&#061; {ts '2009-01-06 23
:59:59'})"> "><SPATIALFILTER relation="area_intersection" ><POLYGON>
<RING>
<POINT x="1427074.01374657" y="596810.020728368" />
<POINT x="1429830.95443664" y="596810.020728368" />
<POINT x="1429830.95443664" y="592945.463874963" />
<POINT x="1427074.01374657" y="592945.463874963" />
</RING>
</POLYGON>
</SPATIALFILTER></SPATIALQUERY></GET_FEATURES></REQUEST></ARCXML>
END

my $server = <<SERVER;
http://maps.baltimorepolice.org/servlet/com.esri.esrimap.Esrimap?Servi
+ceName=BaltimorePolice&ClientVersion=3.1&Form=True&Encode=False
SERVER

my $response
= $ua->post("$server",
{ ArcXMLRequest => "$string",
FormCharset => 'ISO-8859-1', BgColor => '#000000', JavaScriptFunction 
+=> 'parent.MapFrame.processXML', FooterFile =>
'', HeaderFile => '', RedirectURL => '' });

if ($response->is_success) {
     print $response->content;  # or whatever
 }
 else {
     die $response->status_line;
 }

However, instead of getting the response like in Firebug (which is exactly what I want), I'm getting this:
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=ISO-8859-1
+"><HTML><HEAD><TITLE>Default Form</TITLE><!-- Title must match jsForm
+.htm's title --><SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript">

+n="1.1"><RESPONSE><ERROR machine="BPDMAP1" processid="2008" threadid=

parent.MapFrame.processXML(XMLResponse);

}</SCRIPT></HEAD><BODY BGCOLOR="#000000" onload="passXML()"><FORM ACTI
